Implementation of Frames for timecode string. See Vtc.Framestamp.smpte_timecode/2 for more information on this format.

This struct is used as an input wrapper only, not as the general-purpose Premiere ticks unit.

By default, this wrapper does not need to be used by callers, as the string implementation of the frames protocol calls this type's impl automatically. Only use this type if you do not wish for the parser to fall back to feet+frames parsing as well.
