Changes in RenderMan for Houdini 25.1

• Solaris: RenderMan now respects the thread settings in husk.  RMAN-16592
• Solaris: "light group" and "visible in refraction" ligth attibutes now correctly working.  RMAN-20589
• Solaris: If you are using a Shutter of 0.0, 0.0 (for example, to turn off motion blur), XPU will now render properly.  RMAN-20621
• Fixed a problem that would cause Stylized Looks to crash within Houdini.  RMAN-20661
• If you were using XPU to render to "it" and resized the display window, XPU would have crashed.  This is now fixed.  RMAN-20237
• When rendering interactively in Houdini, XPU would not render in-memory volumes.  This is now fixed.  RMAN-20780
