This is based on the previously used, simple TRAC form
with new description language.
We can iterate on it to improve as needed.

If a supported tag has a class, e.g "<i.bold>" it is ignored entirely;
so for example "<i.bold>Hello</i>" would be converted to "Hello{\i0}"
instead of the intended "{\i1}Hello{\i0}".

Allows to output LRC with more precision than standard centiseconds.
Time base is determined by number of requested digits.

Apparently files with milliseconds exist in the wild. And since it cost
nothing to support arbitrary number of digits, extend format to support
that.
Depending on number of digits, the time base of fractional part is
changing. Most LRCs use 2 digits and centiseconds base, but subs with 3
digits and miliseconds exist too.
Set internal time base to AV_TIME_BASE, which in parcitice allows to
hold microseconds with 6 digits. Totally artificial, but who knows maybe
someone wants that.

I also tried replacing some of the instructions by more elaborate ones
using masks, but I found no performance gain significant enough to be worth
maintaining two code paths, so this implementation merely replaces the AVX2
implementation by drop-in AVX512 equivalents.

The use of this function is gated behind avx512icl so that it doesn't
downclock on Skylake.
The end of 8-bit/pixel_code_string() is signalled with two zero bytes, so we
should read those from the buffer instead of one. We keep supporting though our
own buggy encoder which only put one zero byte there.

Initially, avcodec/srtenc.c was outputting CRLF [1]. Later, a real SRT
muxer was added [2], which outputs LF. The original srtenc.c was
converted to use the muxer [3], changing its output to LF, except for
newline characters within subtitle text.
Fix this to avoid producing SRT files with mixed line endings.
