//
// Passed the value of a loop point tag, converts it to numbers.
//
// This may be of the form 00:00:00.00 (HH:MM:SS.ss) to specify by play
// time. Various parts may be left off. The only requirement is that it
// contain a colon. e.g. To start the loop at 20 seconds in, you can use
// ":20", "0:20", "00:00:20", ":20.0", etc. Values after the decimal are
// fractions of a second.
//
// If you don't include a colon but just have a raw number, then it's
// the number of PCM samples at which to loop.
//
// Returns true if the tag made sense, false if not.
