generating a seg fault if no default and no config file provided.
Fixes#1197
This was likely introduced by the combination of fixes for some issues
with the config parsing and some updates to the as<T> method a while
back. This edge case on the handling of the config pointer with as was
not overlooked in the earlier testing.

The default formatter has hardcoded ratio at which the long options are
aligned. It's currently 1/3 of the column, which makes the default look
awkward:
```
-h, --help Print
--option Something
```
A ->long_option_alignment_ratio(6/30.f) allows output to look like this:
```
-h, --help Print
--option Something
```
The 1/3 ratio is also bad if you want to print "descriptive" long
options on a single line, because then you might want to increase the
column width, but that means you waste more space on short options.
e.g. ->column_width(46)
```
-l, --very-descriptive-long-option Something
```
vs. ->column_width(38)
```
-l, --very-descriptive-long-option
Something
```
vs. ->column_width(38) ->long_option_alignment_ratio(6/38.f)
```
-l, --very-descriptive-long-option Something
```
Any absolute offset `X` can be set as `X/column_width`, so provide a
ratio-based interface.
I would have prefered to give an absolute integer offset, but we still
have to preserve the functionality that does 1/3 if user changed
nothing, which means that ratio-based interface is simpler.
I don't have a good idea for the name, "short_option_ratio" might work
as well.
The setter does not sanity check that the value is in [0;1] range.

I am starting to use CLI11 in a project and I came across an
inconvenience in code like this
```c++
const std::string description(std::format("description"));
app.add_flag("--flag", description);
```
As far as I can tell. I cannot directly use the description here. The
reason seems to be to distinguish between assignment and description. So
only `const std::string` or `const char*` and so on can be used here.
But a `const std::string &&` can not be used.
With the changes in the PR the code can also be written like this:
```c++
app.add_flag("--flag", std::format("description"));
```
The `add_flag` function can then be used with a const string or an
rvalue reference to a string.
A bit OT: I was a bit confused by this part of the existing comment ` if
a variable string is passed that variable will be assigned the results
from the flag` I think this might be wrong, but I am not sure.

**Short description**
Application fails with `CLI::ConversionError` in some locales if the
application locale is set.
**Root cause**
CLI11 uses `std::stringstream` to format default value and
`strtol`/`strtod` to parse them back. The first method adds
locale-specific thousand separators but the second method parses the
number only up to the first separator. This causes an exception when the
same value is converted to string representation and then parsed back.
Examples: in _en_US_ locale 1234.56 is "1,234.56" and in de_DE locale
1234.56 is "1.234,56".
**Reproduction**
```c++
#include <string>
#include <CLI/CLI.hpp>
int main(int argc, const char **argv)
{
std::locale::global(std::locale(""));
CLI::App app{"Bug report app"};
long foo;
app.add_option("FOO", foo, "Foo option")
->envname("FOO")
->default_val(1234567);
CLI11_PARSE(app, argc, argv);
return 0;
}
```
Output:
```
$ g++ -Wall -Wextra -I CLI11/include/ cli11-bug-locale-string.cpp -o cli11-bug-locale-string
$ for locale in C en_US de_DE fr_FR de_CH; do echo "locale $locale"; LC_NUMERIC=$locale.UTF-8 ./cli11-bug-locale-string && echo OK; echo; done
locale C
OK

locale de_CH
OK
```
**Fix description**
The fix strips group separators from the input string. This extends a
bit the logic introduced in change #968 for `_` and `'` separators.
There are no unit tests for the change because it requires to have all
mentioned locales to be installed in the system.

CLI11 code prints the command-line arguments in reversed order in the
error message.
Code to reproduce:
```c++
#include <string>
#include <CLI/CLI.hpp>
int main(int argc, const char **argv)
{
CLI::App app{"Bug report app"};
std::string foo;
app.add_option("--foo", foo, "Foo option");
CLI11_PARSE(app, argc, argv);
return 0;
}
```
Reproduction:
```
$ g++ -Wall -Wextra -I CLI11/include/ cli11-bug-order-in-error.cpp -o cli11-bug-order-in-error && ./cli11-bug-order-in-error --foo bar --fizz buzz
The following arguments were not expected: buzz --fizz
Run with --help for more information.
```
Expected result:
```
The following arguments were not expected: --fizz buzz
Run with --help for more information.
```
Fixes#1156
For option groups removes inheritance of the footer and help option, so
those are not printed by default for option groups. It is still possible
to set them again on the option group.
