TimeMachine NKPD

Does a per-pixel time offset on the image, based on a secondary mask input.

This is sort of a copy of Houdini's Time Machine. Takes an image sequence plus a mask, then offsets the image in time based on the input mask as follows:

• Pixels with a mask value of 1 will be offset by the number of frames set in the "frames" knob.
• Mask values of 0 return the image at the current frame.
• Values between 0-1 will return an interpolated offset.
• Mask gets clamped to 0-1, so values <0 and >1 are not accounted for.

Very simple as it stands, but could be a good example of rebuilding a gizmo's internals using callbacks.
