Add Breton and C’hwerty -maths- layout.

[Envel-Pichon]

Add Breton language (dictionary generated from a corpus of the Breton Wikipedia, a little less than 5 000 words).
Add the c’hwerty - maths layout (originally from drouizig.org, modified to use mathematical signs and median point).

As I'm not a pro-developer, I tried to do my best to understand the documentation.
I hope it'll work.

I wrote on the keybr Discord to give more explanation about Breton specificity on "c’h" an "ch" which are bigramm and trigramm directly obtained from pressing a single key on the c’hwerty layout.

Hi and thanks for your concern ;)

I read that the import of the keyboard failed.
Maybe it's because of the geometry ?
I just cp the fr-fr keyboards lines and changed what I thought what needed to match the c’hwerty-maths layout.
I also saw there were an invalid dead key to type the median point · (alt left + ²).

I put the json file for c’hwerty-maths obtained from the layout tool found in keybr in the feedback-and-support chanel of the Discord, maybe it'll be more suitable to work with than the .klc file ?

Have a nice day,

Envel
