T-pose generator for sim

T-pose generator:
This tool streamlines the process of preparing a bind pose for characters in animation scenes, optimizing them for cloth simulation in Houdini. It automates key tasks, including:
- Keyframing all controls at animation start (frames 1000 and 1001).
- Positioning the character in a perfect T-pose at frame 970, including adjustments for custom attributes like IK roll and softness.
- Switching hands to FK mode at frame 970, blending smoothly back to the original setting at frame 1001.
- Keying constraints and anim layers, ensuring proper transitions (e.g., weight changes at frames 970 and 1001).
- Optional "Freeze 5 Frames" feature, keeping frames 970-975 and 995-1000 static.
- Ensuring tangents and animation after frame 1001 remain unaffected.
