feat: add mp4ff-mvhevc command line tool

Add an mp4ff-mvhevc CLI with two subcommands following the structure of the
other mp4ff tools:
- info: display the MV-HEVC structure of an mp4 (sample entries, hvcC/lhvC,
  oinf/linf sample groups, vexu/hfov spatial metadata, trgr)
- add: mux HEVC (Annex B with -fps, or an existing mp4) into a single-track
  MV-HEVC mp4 with hvcC (+lhvC for an enhancement layer), oinf/linf sample
  groups for layered input, and optional Apple spatial-video metadata
  (vexu/hfov) via -spatial

Access units are split at the first slice of each base-layer picture
(first_slice_segment_in_pic_flag), so multi-slice pictures are not split into
separate samples. Composition offsets (ctts) are carried over when re-muxing
an mp4 input. A conformant vmhd is written. As both views share one track, no
track group box is emitted.

Registered in README, .goreleaser.yml and the Makefile.
