Simple parser that only parses frame information.
This helps avoid requiring the software decoder on init to decode a
single frame, since the decoder can be quite slow.

In general, a provider code corresponds to a company/organization, and
the name should be that of the company, not of a given feature.
The feature is signalled in the "provider oriented code".
The exception is HDR Vivid, where the code 0x0004 indicates the HDR Vivid
feature itself rather than CUVA (China UHD Video Industry Alliance),
according to the UHD World Associations 'HDR Video Technology Part 2-1
Application Guide to System Integration' document.

The check to return on EOF should not be inside a block that will not be entered after reaching EOF.
Should fix "libavcodec/bytestream.h:144:27: runtime error: applying zero offset to null pointer".

- proper pts for packets. leaving it blank leaves it up for guessing,
but the guess doesn't take seeking into account, causing weirdness.
- clamp to 0 when seeking to negative ts. libopenmpt docs are unclear on
this but not doing this causes an immediate EOF when seeking backwards
to the beginning in mpv.
- only set song duration and packet pts when they are non-negative and
in int64 range. NaNs count as out of range. this isn't a fix for any
specific issue but might be helpful still, and shouldn't break
anything.
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.

Note that Codec Descriptors are not written for all these ai** codec tags, and no
considerations were ever made to ensure parameter sets are present in muxed packets.
Their usage may result in unplayable files if parameter sets are only available
in extradata (Default behavior for x264 encoding when combined with this muxer).

BIO_get_new_index() is static counter meant to get index for custom bio
type definition. As we can read in the documentation:
> Note that BIO_get_new_index() can only be used 127 times before it
> returns an error.
We cannot call it repeatedly, because it will fail eventually.
To my understanding the index is not needed in our use and we could
safely use BIO_TYPE_NONE. Documentation states:
> type can be set to either BIO_TYPE_NONE or via BIO_get_new_index() if
> a unique type is required for searching (See BIO_find_type(3))
We don't use any search related functions.
