Also add new options from esp32 dev board to alks.

What these new options added to beginners? Isn't that counterproductive?

[cleveHEX]

Beginners do not have to tamper with these values and it’s better to have them changeable, so you can use alks for everything. Those are only for supporting newer revisions of devkit.

Ok, it makes sense.
