mrv2 v1.0.0

[ggarra13]

This the release of v1.0.0 of mrv2.

v1.0.0

• Improved performance of scrubbing when audio is turned off in the timeline
  section of the main UI. Helps in scrubbing 4K movies.
• Made readBehind cache expand freely when using Gigabytes in Settings
  to improve the performance of scrubbing 4K movies.
• Fixed a crash when showing an .otio timeline with markers at start or when
  dragging a clip with .otio markers.
• Added display of transitions (Dissolves) to Timeline Viewport. If you edit
  a clip that has transitions, those will be removed before the move.
  Currently, there's no way to add transitions again (you need to edit the
  .otio file manually, or convert it from a Non-Linear Editor format).
• You can also not currently move or scale the transitions.
• Fixed default versioning regex for '_v' to match UNC paths on Windows.
• Fixed version of USD which showed MaterialX version instead.
• Updated USD to v23.11.
