Timescale in Edit List Boxes is not adjusted when mvhd timescale changes

[chartelt]

When using FragmentedMP4Builder for example, usually the resulting movie`s timescale gets adjusted to the timescale of the video track(s) which is okay.
But currently any edit list entries get copied from the source file into the resulting file. But then elst entries become invalid since duration values refer to movie timescale in mvhd which has acutally changed.
Possible to adjust the duration values in there according to the changed timescale value from mvhd?

Reopened since I was wrong - different timescales are necessary for different entries:
segment_duration -> in units of the timescale in the Movie Header Box
media_time-> in media time scale units, in composition time
