transcrypt v2.2.1

This release fixes a bug introduced in version 2.2.0 that made transcrypt incompatible with the LibreSSL version 3 and later, which particularly affected users on MacOS 13 "Ventura" which shipped with the LibreSSL project's binary version 3.3.6.

Feature summary

Fixed

• Compatibility fix for LibreSSL versions 3 (and above) especially for MacOS 13 Ventura, to more carefully apply a work-around required for OpenSSL 3+ that isn't required for LibreSSL 3+ (#147 #133)
