Fix various bugs in subtitle/ccap verification.

Check that subtitles don't overlap reel boundaries, and fix a few tests that trip this check. Fix confusion when calculating subtitle timings during verification where the picture asset frame rate was being used rather than the subtitle asset's edit rate. Do the subtitle timing verification for Interop as well as SMPTE subtitles. Take tags into account when checking subtitles, even though Bv2.1 says they should be set to 0. Rename Time::as_editable_units to Time::as_editable_units_ceil and add a _floor variant, then use that to round down when checking reel boundary overlaps.

Comment fixes.
