Closes #1499

Work to be done in this PR:

  • Change Dtvcc::new() to create Dtvcc using ccx_decoder_dtvcc_settings as done here
  • Create a new extern C fn ccxr_dtvcc_init() in lib.rs and use this at all places where dtvcc_init() is being called. (Probably add a new struct field to lib_cc_decode like dtvcc_rust and store Dtvcc there instead of using the dtvcc field)
  • Similar for dtvcc_free()
  • Change ccxr_process_cc_data to use Dtvcc from dec_ctx instead of creating a new one

Additionally to fix mp4 code flow:-

  • Call the corresponding rust function here and pass Dtvcc as done in the above steps

All checkmarks are done.

But with this sample file I am getting some memory leaks (in debug mode) -- error shown in here

Command used:

./ccextractor ~/Downloads/cc/test_dtvcc.ts --autoprogram --out=ttxt --latin1

@IshanGrover2004 is this working fine now, after fixing the memory leaks?

Some weeks before PR was ready.
But now when I again visited & ran sample on the rebase with master code, it just crashing at ccx_decoders_708_output.c:591 in dtvcc_writer_init
