Add support of syllable lyrics

[dm-vodopyanov]

Syllable lyrics is an extension of enhanced LRC format, for more see here: https://en.wikipedia.org/wiki/LRC_(file_format)#A2_extension:_word_time_tag

Example:

[00:00.00] <00:00.04> When <00:00.16> the <00:00.82> truth <00:01.29> is <00:01.63> found <00:03.09> to <00:03.37> be <00:05.92> lies 
[00:06.47] <00:07.67> And <00:07.94> all <00:08.36> the <00:08.63> joy <00:10.28> within <00:10.53> you <00:13.09> dies 
[00:13.34] <00:14.32> Don't <00:14.73> you <00:15.14> want <00:15.57> somebody <00:16.09> to <00:16.46> love

The request is to add an ability to differentiate syllable lyrics from usual "Synced" LRC files in LRCLIB and LRCGET and correctly display them in LRCGET.

@tranxuanthang Is there a way to get Syllable lyrics?

[tranxuanthang]

@Tox1cPhantom There isn't one for now. I'm still not so sure if it is worth it, because word-by-word sync will be much more time-consuming, so the contribution rate to this format might be extremely low.

But who knows, if there is high demand for this, then it will be added to LRCLIB and LRCGET someday.

@tranxuanthang there is no need to create syllable lyrics manually, one can download syllable lyrics from Apple Music in TTML format and convert them into syllable LRC lyrics.
