Add support for conversion from Falcon Player to other formats

Previously, only conversion to the Falcon Player .fseq format was
supported.

With Vixen 3 support coming for output directly to the Falcon Player's
.fseq file format, this will allow users to convert to other formats
as well as importing that sequence into xLights/Nutcracker by
converting to .xseq and adding more effects or testing with the
xLights/Nutcracker preview.
work on single strand effects.
