We have this:

x TemporalOffset 0: 0 1: 1 2: 1 3: -2 4: 1 5: 1 6: -2

We want to transform it into this:

x DTS PTS 0: -1 0 1: 0 3 2: 1 1 3: 2 2 4: 3 6 5: 4 4 6: 5 5

We do this by bucket sorting x by x+TemporalOffset[x] into mxf->ptses, then settings mxf->first_dts = -max(TemporalOffset[x]). The latter makes DTS <= PTS.
