Added Huntsman Elite layout.

Not being good with C++ I would say that this is not a final release, it is more like something to let people owning a huntsman to modify the lightening while waiting your final release. I tested it and it works.

You'll need to add the matrix_layouts/razerhunt22.json to the installation in data/meson.build too. (Once this has landed, I'll open a pull request for the German layout).

The layout looks awesome, thanks a lot!

I've fixed up some medium to small things, incl. making the last row look better, I guess you had a problem where it moved row10 as second row which seems to be because QJsonObject sorts automatically by alphabet, so row1 -> row10 -> row2 :) Using row01, row02 etc makes it work.

And of course sorry for the delay in review..
