Added #define to use Window's builtin routines for conversion routines.
Explicit casting via static_cast to/from types was needed for c++11 compliant compilation
as an appropriate constexpr for size selection (e.g. be16toh vs. be32toh) is not
available until C++11.

Todo:  support compilation C++14,C++17, C++20.

If fde length reports longer than the section length, we need to abort parsing as the input is invalid.

DW_EH_PE_omit is FF so it cannot be a case
of encoding_lower8. Instead it can be a check against
the complete encoding.

updated to build with use_eflio in scons by default.  removed lots of std:: qualifiers that weren't needed

simplified interface to just return const pointers instead of shared ptrs.  no one needs ownership of anything
