- version update to 1.6.44:
* Hardened calculations in chroma handling to prevent overflows, and
relaxed a constraint in cHRM validation to accomodate the standard
ACES AP1 set of color primaries.

* Removed the ASM implementation of ARM Neon optimizations and updated
the build accordingly. Only the remaining C implementation shall be
used from now on, thus ensuring the support of the PAC/BTI security
features on ARM64.

* Fixed the pickup of the PNG_HARDWARE_OPTIMIZATIONS option in the
CMake build on FreeBSD/amd64. This is an important performance fix
on this platform.
