Remove mod-5 limitation

[blaze077]

There is a mod-5 limitation on the 24fps ranges similar to YATTA. When dealing with a mixed 24/30p source, if the 24fps range is not mod-5, Wobbly (and YATTA) will just move the range to be mod-5 compatible (except if it's at the end). This limitation in YATTA was present due to Avisynth not natively supporting VFR, but in Wobbly, this shouldn't be a problem at all due to Vapoursynth's native VFR support.

I just tried to do stuff with vfr in vapoursynth a few days ago but the resulting timecodes were rounded with very low accuracy (like +-1fps). It could've been the fault of the source filters but then lsmash libav and ffms2 would have to have the same issue. I am not sure if vapoursynth can handle vfr correctly.

I'm pretty sure that's just a video container related problem. L-SMASH-Works as it is does not support VFR. Vapoursynth handles VFR just fine given that you feed it the correct frame rate values.
