de796c95f0 tttocea608: refactor to fit more scenarios
- Report a latency:
  By design, tttocea608 will output buffers in the "past" when
  receiving an input buffer: we want the second to last buffer
  in the buffer list that we output to have the same pts as the
  input buffer, as it contains the end_of_caption control code
  which determines when the current closed caption actually gets
  displayed in pop_on mode. The previous buffers have timestamps
  decreasing as a function of the framerate, for up to potentially
  74 byte pairs (the breakdown is detailed in a comment).

  The element thus has to report a latency, at 30 frames per second
  it represents around 2.5 seconds.

- Refactor timestamping:
  Stop using a frame duration, but rather base our timestamps on
  a scaled frame index. This is to avoid rounding errors, and
  allow for exactly one byte pair per buffer if the proper framerate
  is set on the closed caption branch, and the video branch has
  perfect timestamps, eg videorate. In practice, that one byte
  pair per frame requirement should only matter for line 21 encoding,
  but we have to think about this use case too.

- Splice in erase_display_memory:
  When there is a gap between the end of a buffer and the start
  of the next one, we want to erase the display memory (this
  is unnecessary otherwise, as the end_of_caption control code
  will in effect ensure that the display is erased when the
  new caption is displayed). The previous implementation only
  supported this imperfectly, as it could cause timestamps to
  go backwards.

- Output last erase_display_memory:
  The previous implementation was missing the final
  erase_display_memory on EOS

- Output gaps

- Write more tests

e158f4ef88 meson: rename cargo.py to cargo_wrapper.py
Fix 'cargo build' on Windows as its $PATH includes $PWD, it seems to
pick our script rather than the actual cargo.

cbb1912e99 meson: check for dav1d dep
Needed to build dav1d-sys which is required by the dav1d decoder plugin.

Exclude the plugin if the dep isn't found, preventing the build to fail.

317679fec3 meson: add gstreamer-rs deps
Fix race when building from gst-build as we need to be sure that all
these deps have been built before starting building gst-plugins-rs which
will build gstreamer-rs.
