Includes code for uploads, customsize, dateformatting,
forcing timestamps, and hiding the useless GIF output of the combine
video node, but lacks the video preview code and testing.
-Restore original name of 'VHS_LoadVideo' to 'VHS_LoadVideoPath'
-Restore LoadVideoUpload and bring its features up to parity with LoadVideoPath and UploadVideo
-Rename 'input' and 'effective' variables to 'original' and 'actual'
-Add guard clause for undefined video widget value
-Add PIL fallback to LoadVideo to support video types not supported by opencv2, such as webp, apng, and mjpeg. Changing frame rate is not supported in this mode. The output log will inform you of this when the fallback is used.
-Removed VHS_LoadVideoUpload node
-Renamed VHS_LoadVideoPath to just VHS_LoadVideo
-Added a video_info output to LoadVideo which includes more information, such as the frame count, fps, duration and frame time for the input video and the output frames
-Added a new node UploadVideo which includes the functionality of LoadVideoUpload insofar as copying a video to the input folder but also allows the user to upload to temp instead for testing so as not to clutter the input folder. Uploaded videos now go to a subfolder, 'VHS_upload'.
-Added gif preview to UploadVideo so uploaded videos can be viewed on the node when selected.
-Fixed autoplay for gif preview on VideoCombine, still not working for videos on UploadVideo node.
-Added drag and drop for videos on UploadVideo node.
-Changed 'force_frame_rate' to 'desired_frame_rate' because it cannot be forced in PIL fallback, this is an effort to communicate this to the user
The base implementation from pngs uses String.fromCharCode,
but that causes overflow from having too many arguments when decoding
video files, likely since no chunking is done and everything is embedded
as a single monolithic json
As an additional benefit, data is now properly decoded from utf-8
instead of being interpreted as utf-16
