Wishlist: select a start DPX frame (and duration)

[eddycolloton]

Allow user to begin the rawcooked process at a particular frame of a dpx sequence, and stop at a particular frame of a dpx sequence (instead of the whole sequence).

This could benefit processing large sequences in segments, or creating excerpts. Excerpts could be a significant benefit for intellectual control of a sequence that contained several subsections.

This ticket arose around discussion of a separate issue ticket (#287 #287).

Would be something like rawcooked YourDirectory -start_number 86000 -t 5.
(options similar to FFmpeg, but duration is in second, I guess I need a duration option with a count of frames too, so -frames if I still want to copy a bit FFmpeg options).

[retokromer]

I guess, like in FFmpeg, the parameter -t should allow both a number of seconds and a timecode.
