Fixed random crashes in the Houdini (main) Python 3.11 build due to incompatibilities with Houdini's PySide2 5.15.2 package.

Bumped up Houdini's PySide2 to 5.15.15, which has complete Python 3.11 support.

Packages - Add HOUDINI_SCRIPT_PATH legacy support

• Update hou.ui.loadPackage/unloadPackage/loadPackageArchive to supportscripts located in 'scripts/python` sub-folders.

Have ML Regression Train use numpy==1.26.0 instead of numpy==2.1.0. This gets rid of warnings and prevents potential incompatibility issues with torch.

Ensure that ML Regression Train is capable of GPU training on windows machines by obtaining the torch package from download.pytorch.org.

Mantra will now properly save out cryptomatte metadata when saving multi-part OpenEXR images using the OIIO image driver.

Fixed a possible precision issue when computing instance motion segments. This might have caused over (or under) blurring when the time segments on the stage didn't align with shutter times.

The context menu for a USD prim with no variant sets will now look up the scene graph hierarchy for any ancestor prims with variant sets, and allow setting those variants from the menu. This makes it much easier to choose variants on an asset by bringin up the menu for any prim within the asset.

Using the scene graph tree to make a prim visible when an ancestor prim is marked as invisible now works as expected. Ancestor prims are marked visible, and the invisibility marker is moved onto the child prims (except along the path of prims we are marking as visible).

Fixed a potential crash in the Crowd MotionPath Edit SOP.

Fix crash in Texture Optical Flow and Texture Feature SOPs when input is a volume with multiple primitives.

Fix regression in the Rig Pose SOP's viewport tool where handles were rendered in the wrong space whenever its owner Object node was transformed.

Added hotkey handling for Set Normalize Value Mode in Animation Editor.

Fixed issues where subsequent linking rules that affect a light were overwriting previous ones. This was most egregious of which was when multiple geometry centric rules are defined.

Fixed a problem in the material linker and light linker that would cause the edit prim pattern dialog to unintentionally reopen to the next rule when you close it.

Enabled various compiler optimizations.

Fixed a rare bug that made Fractal Noise and Fractal Noise 3D COPs produce NaN's.

When unpacking USD to SOP geometry, the 'usdconfigreversepolygons' attribute is now added to primitives where the winding order was reversed. When round-tripping back to LOPs, this restores the original orientation without needing to manually adjust SOP Import parameters.

Fixed a bug in the USD Animation Import SOP which could cause the animation to be imported at the wrong USD timecode (off by one).

Added new Chladni Cymatic Patterns COP to perform simple tileable interference patterns.
