Flicker to hover with current brightness as the middle value

[Joshfindit]

Describe the problem you have/What new integration you would like

When flicker is called, it dims significantly, seeming to make the current brightness the max brightness, then the natural flicker rarely if ever lands on the brightness again.

Please describe your use case for this integration and alternatives you've tried:

Ideally, I would like if I was able to set the brightness to an arbitrary value, then have a flickering 'candle light' that stays around that brightness

Additional context

There will also be logic to consider when brightness starts at 100%. I would still prefer that 100% be the 'average' brightness. Possibly with a mapping like 101% = 99%, 105% = 95%, 140% = 60%, etc

Both this and esphome/issues#555 may end up being closed with the same code change

Yeah that's what the flicker effect is supposed to do - I will merge this into the mentioned issue, because it's not really a feature request.
