d0db66d61e transcriberbin: implement dynamic language update 
Previously, transcriberbin only supported updating translation languages
while playing by resetting the state of the transcriber to NULL
beforehand, as for instance the speechmatics transcriber needs to
reestablish a connection to request new languages.

Now that translationbin exists, we can request new languages without
restarting the transcriber (this commit also implements support for this
in translationbin).

There is some code duplication as the old method still needs to be
supported, and not all code was trivially factorizable, but after some
refactoring most of the code for updating languages is shared
nevertheless.

cece286fe8 ceax08overlay: fix field lookup for s334-1a 
As stated in the spec:

> Bit b7 of the LINE value is the field number (0 for field 2;
> 1 for field 1). Bits b6 and b5 are 0. Bits b4-b0 form a 5-bit unsigned
> integer which represents the offset [..]

Here, b7 is the most significant bit, this is what both cccombiner
and ccconverter agree on.

The overlay elements previously looked at the least significant bit,
which led to garbled text when both fields were actually present
in the CC meta.

71121a2380 aws: reimplement two separate wrappers for translate and transcribe 
The original awstranscribe element has grown too complex when
integrating translations for reasons that in retrospect were wrong:

As awstranscribe outputs words one by one, I decided we wanted to
perform translations there with larger sentences if available, but an
alternative design where a separate translation element is composed
downstream is also possible, as long as that element accumulates words
and enough latency is set on the transcriber.

An important difference is that the new elements do not expose unsynced
pads, this use case is instead now served by simple messages on the bus.

The elements should otherwise be at feature parity with the original
element.

A higher-level bin is also provided for convenience (and usage within
transcriberbin): translationbin.

A transcriber element can be provided to this bin, which exposes an
always audio sink pad, and an always text sink pad (for the
transcripts).

Additional source pads can be requested for translations, for now the
bin always uses `awstranslate` as the translator, but this can be made
configurable.

This element is usable as a transcriber in `transcriberbin`.

7e2a4cf61c cdg: fix typefind error with specific file sizes 
Currently, the typefind logic for cdg can cause errors on files
with all conditions below:
- size multiple of NB_WINDOWS * CDG_PACKET_SIZE (8 * 24) = 192
- size less than TYPEFIND_SEARCH_WINDOW (28800)
- extension different than .cdg

With those conditions, the cdg typefind function may be the last one to
execute and cause gsttypefindhelper.c::helper_find_peek to return
GST_FLOW_EOS, and if it's the final call will then be turned to
GST_FLOW_ERROR in typefind.

That is because cdg's typefind will perform a last call to
typefind.peek(len, CDG_PACKET_SIZE) which is outside the range of typefind
(from 0 to len - 1).

Reproducer with file from cdg tests:
```
head -n 28608 BrotherJohn.cdg > BrotherJohn_short.bit
gst-play-1.0 BrotherJohn_short.bit
```

Fix this by correcting the loop bounds in the cdg typefind
logic. Perhaps the typefind helper logic should be rewritten to avoid
such cases too.

Then the example above works and unrelated files aren't affected by this
in typefind anymore.
