Add LTX-2 Support (#644)

* WIP, adding support for LTX2

* Training on images working

* Fix loading comfy models

* Handle converting and deconverting lora so it matches original format

* Reworked ui to habdle ltx and propert dataset default overwriting.

* Update the way lokr saves to it is more compatable with comfy

* Audio loading and synchronization/resampling is working

* Add audio to training. Does it work? Maybe, still testing.

* Fixed fps default issue for sound

* Have ui set fps for accurate audio mapping on ltx

* Added audio procession options to the ui for ltx

* Clean up requirements

+        For models that support audio with video, this option will load the audio from the video and resize it to match
+        the video sequence. Since the video is automatically resized, the audio may drop or raise in pitch to match the new
+        speed of the video. It is important to prep your dataset to have the proper length before training.

+        When loading audio, this will normalize the audio volume to the max peaks. Useful if your dataset has varying audio
+        volumes. Warning, do not use if you have clips with full silence you want to keep, as it will raise the volume of those clips.
