Feature Request: Support for Exponential Moving Average

[PowerrNuller]

Is your feature request related to a problem? Please describe. With mav built in - support for emav - exponential moving average would be nice - and I suppose easy to configure.

Describe the solution you'd like Addition of emav as an argument to mpf.plot ***kwargs with support in mpf.make_mpf_style() to assign custom colors

Describe alternatives you've considered Manually calculate and plot? Why not add it?

Additional context Nope.

A reasonable request. Regarding custom colors, is there any reason not to use the existing mavcolors? Do people every want to plot both SMA and EMA?

Not really, it is either SMA or EMA (or else), I personally prefer EMA, more adaptive. But it's a matter of 'tastes'

Yes - I think having that flexibility helps and keep the library dynamic to help different traders with different sytles

Has anyone managed to add the emav successfully? Thanks.
