9699b49098 [util][formulas] Rename normalize_angle function to normalize_azimuth 
For normalizing longitudes, the normalize_longitude function is
used instead.

06eb057fa9 [formulas] Use assignment operator on the same line for consistency 
Other changes include the update of series expansion function
calls, as the template arguments are reversed.

19f06fa04e [util] Reverse template argument order for series expansion functions 
In some cases, this allows the caller to ignore the CT template
argument, as it is deduced from the argument list.

dedccdbdae [formaulas][util] Define coefficient containers for computing series expansions 
The coefficient containers are defined as structs in
series_expansion.hpp file. They allow the caller to
compute expansions without specifying the size
for the output array.

d591d7a7bb [util] Use existing normalize_spheroidal_coordinates class for normalizing an angle 
- This should normalize the given angle in range (-180, 180].
- The function normalize is also moved from math.hpp to
normalize_spheroidal_coordinates.hpp where it is renamed
to normalize_values
