Allow passing extra channel rendering options to Make_Movie script (see ...

...#12037)

Added new argument to script; ChannelsExtended. The accepted format to allow for passing channel window range and color, with the format 'idx|min:max' having both '|min:max' and '' optional, but when both are present order must be respected.
ex: ChannelsExtended=2|0:250,3|50:100

If both Channels and ChannelsExtended are passed, the latter takes precedence.
