add support for WS2811 timing (IEC-194)

[sterisa]

Change description

Within the led_strips component:
Added a new led model in led_strip_types
Added the corresponding timing in led_strip_rmt_encoder (I had to move reset_ticks definition up to be able to edit it for WS2811

I tested on a WS2811 50 led strip
Note WS2811 is RGB, not GRB. I will put that change in later

@sterisa Thanks for your contribution. This PR proposed a new way to set the pixel order in the user code, I think it can also help with your WS2811: #344

A little overkill, but I am fine whatever you decide. My WS2811 timing changes are pretty small and independent of the RGB vs GRB handling. Should I revert my RGB changes?

Hi @sterisa Thanks for your time! #344 just got merged. Now it should be possible to support any R/G/B/W order.

The timing configuration of WS2811 in this PR is still valuable. Could you please rebase your branch and fix the conflict?

Done, this should be the minimal change for the WS2811 timing
