nodes load image sequence

Load Image Sequence

Load an image sequence from a folder. The current frame is used to determine which image to load.
The UX need improvements but you can use it as follow:

• If current_frame is -1, it will load all the frames matching the pattern.
• If the path contains a * it will glob the paths using it.
• If range is provided (for instance 0-10 to load frame 0 to 10) current_frame is ignored.
