avformat/lrcdec: support arbitrary precision timestamp
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.
