need canon eos m6 mark ii support

[jheidemann]

I see cr3 support is on the canon_cr3 pull request (yea!).

That pull request has many cameras, but not the EOS M6 Mark II. It seems like data/cameras.xml needs to be informed about this new model. What is required to do so?

IMHO you'd be better off asking directly in the CR3 related PR.

Here is a patch adding support. It was given to me by Daniel Vogelbacher (thank you!).
It works for me when I build darktable with it.
