Mateusz Loskot 6e3ccc00b1 Remove dependency on Boost.StaticAssert (#207)
Replaced BOOST_STATIC_ASSERT with C++11 binary static_assert,
with empty message.

In future, this should make it possible to automatically refactor
into C++17 unary static_assert using clang-tidy and
its modernize-unary-static-assert check.

Closes #106
