Improve: Dancer emoji

[SpangleLabs]

As discussed in #366 , the openmoji dancer/woman dancing emoji could do with improvement to align with other platforms.
Apple's depiction with a red dress has become more and more standardised, especially as the gender was differentiated with the addition of man dancing. Google, Microsoft, and Samsung have all switched to having a woman in a red dress. So it would be useful for openmoji to move in that direction too, such that it can be a better drop-in replacement.

The man dancing emoji could also be drawn more in line with other platforms, with an addition of a 70s-era suit?
