Description:

Add support SEN6X sensors. Only the SEN66 is available at this time, but the SEN60, SEN63C, SEN65 and SEN68 are scheduled to be released this year.

It looks like some of the defaults may be different between the SEN5x and SEN6x devices?

In the example SEN66 config it has:

    nox:
      name: "NOx"
      algorithm_tuning:
        index_offset: 100
        ...
        gating_max_duration_minutes: 180

But under the nox description below it says:

• index_offset (Optional, integer): NOx index representing typical (average) conditions. Allowed values are in range 1..250. The default value is 1. ...
• gating_max_duration_minutes (Optional, integer): Maximum duration of gating in minutes (freeze of estimator during high NOx index signal). Zero disables the gating. Allowed values are in range 0..3000. The default value is 720 minutes.

Are the defaults different between these two or is the SEN66 intentionally being set to something other than the default? Just wondering about the discrepancy of 1 vs 100 for index_offset and 180 vs 720 for gating_max_duration_minutes.

I think I just made a mistake. The latest documentation doesn't even have these shown in the example. I believe the SEN5X and SEN6X sensors have the same defaults. VOC defaults are different from the NOx defaults and that wasn't handled correctly in the original sen5x component. There is another PR that addresses the default issue with VOC and NOx. It was just merged so I'm updating this PR now.

There has been a significant change to the documentation format too. No more reStructuredText (rst) files. Now it is Markdown (md).

I have updated the documentation to use the new Markdown structure and changes from PR #5176.
