Make Input Whitespace Independent

[AEFeinstein]

The following to RTTTL strings are identical, except the first has spaces and the second does not. When playing on https://adamonsoon.github.io/rtttl-play/ the first will be too slow as it seems to ignore the eighth note default (d=8).

TitleScreen: d=8,o=5,b=376: c6, g4, p, g, e4, f, c, g4, c6, e4, p, g, g4, f, c, e4, c6, g4, p, g, e4, f, c, g4, c6, e4, p, g, g4, f, c, e4, a#, g#4, p, g, d#4, d#, d, g#4, a#, d#4, p, g, g#4, d#, d, d#4, a#, g#4, p, g, d#4, d#, d, g#4, a#, d#4, p, g, g#4, d#, d, d#4, g#, f4, p, g, c4, d#, c, f4, g#, c4, p, g, f4, d#, c, c4, g#, f4, p, g, c4, d#, c, f4, g#, c4, p, g, f4, d#, c, c4, a#, f4, p, g, d4, f, d, f4, a#, d4, p, g, f4, f, d, d4, a#, f4, p, g, d4, f, d, f4, a#, d4, p, g, f4, f, d, d4

I don't think the RTTTL spec mentions whitespace, but I would expect these two inputs to play the same song. I believe the simple solution is to strip all whitespace from the input string before parsing. I can try to write that if you want, but I'm an embedded C programmer and have no JS experience.

Maybe stripping all whitespace is naive, because it would be OK to have in the title. So I guess strip all whitespace after the first : before parsing?
