The `BOOST_LITTLE_ENDIAN` and `BOOST_BIG_ENDIAN` macros, along with the
"boost/detail/endian.hpp" header, were deprecated in boost 1.69.0 and finally
removed in boost 1.73.0.  They are superseded by the BOOST_ENDIAN_LITTLE_BYTE
and BOOST_ENDIAN_BIG_BYTE macros and "boost/predef/other/endian.h" header.

Deprecated: https://github.com/boostorg/predef/commit/32d4581c1689370444f2e565cfbb8421d5071807
Removed:    https://github.com/boostorg/predef/commit/aa6e232bf170ad8b856aff9e7c70334f77441c7f
