Import WLED JSON sequence configurations as FPP overlay effects

[ptr727]

Is your feature request related to a problem? Please describe.
WLED has an active configuration sharing community, sharing custom configurations in JSON format.
WLED configuration and FPP WLED overlay configuration is dissimilar, making it difficult to create overlay effects based on WLED configurations.

E.g.

{"on":true,"bri":146,"transition":7,"mainseg":0,"seg":[{"id":0,"start":0,"stop":302,"grp":1,"spc":0,"of":0,"on":true,"frz":false,"bri":255,"cct":127,"col":[[255,224,160],[255,0,0],[33,192,255]],"fx":81,"sx":67,"ix":141,"pal":41,"sel":true,"rev":true,"mi":false},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0}]}

Describe the solution you'd like
Allow import, via e.g. copy-n-paste, of WLED JSON configuration in FPP overlay configuration.

Describe alternatives you've considered
I keep the WLED config UI and FPP overlay config UI's open, then guess what the matching parameters are called, and experiment to get a similar effect, tedious at best.

Additional context
I submitted a similar enhancement request for the WLED plugin, but given the recent improvements in the FPP overlay config UI, native FPP support would be preferred.
