Generate .cue from timestamp for long program

[Live Musicfs]

Hello get_iplayer team,

Radio 3 Iplayer provides timestamp and track title to seek each piece of music quickly, in long program like concert and “Throughout the Night".

The current Get_iplayer writes these timestamp to "Lyrics" embedded in .m4a file, it will be  very helpful to build a .cue file from it.

However, one problem is that the timestamp listed in webpage and audio player is different. Webpage timestamp is the planned time by editors, while audio player time stamp is the actual time in live broadcast (the time for news and other broadcast is variable).

Best,
Preluder
