This release is mainly small updates and bug fixes focusing on specific platforms, with no new features added.

Changes

Be more selective in use of AVX512 on AMD Zen4 processors. This can be faster (e.g. with 64-way unrolling), but in the current rANS codec implementations AVX2 is faster for certain operations (PR#85).
Add config.h to test programs to help them pick up definitions such as XOPEN_SOURCE (PR#84)
Add FreeBSD to CI testing (PR#83)

Bug fixes

Trivial bug fix to the rans4x16pr test harness when given incompressible data (PR#86).
Make ARM NEON checks specific to AArch64 and exclude AArch32 systems. (PR#82 to fix issue#81, reported by Robert Clausecker)
