mayaMatchMoveSolver-v0.4.4

The v0.4.4 release fixes incorrect solving, has better support for placing markers when using lens distortion

NOTE: It is not recommended to mix this release with v0.3.x. It is recommended to use v0.4.4 only on new projects as there may be some incompatibility opening Maya Scenes created with v0.3.x using v0.4.x - if this is an acceptable problem, feel free to mix and match as needed.

This release also contains a number of features for the MM Renderer (#231), but the Renderer is not installed or enabled by default. Compile from source and enable the CMake build option MMSOLVER_BUILD_RENDERER.

The mmSolver release for Maya 2024 is only supported on Red Hat Enterprise Linux (RHEL) 8, or Rocky Linux 8 and will not work on RHEL 7 or CentOS 7.
