Re: [boost] [modularization] Recommendations

Made pull requests for those libraries to use polymorphic_cast.hpp instead of cast.hpp: https://github.com/boostorg/gil/pull/9 https://github.com/boostorg/statechart/pull/1 https://github.com/boostorg/range/pull/10

Moved cast.hpp to the NumericCast library: https://github.com/boostorg/numeric_conversion/pull/2

I can merge these if there are no objections.
