Keymap: Nordic layouts for ErgoDox, Planck (#3693)

* first verion of skug

* zudvp layer added and new thumb cluster

* move del to arrw cluster and switch places of algr and no_circ

* first verion of skug

* zudvp layer added and new thumb cluster

* move del to arrw cluster and switch places of algr and no_circ

* rework layouts

* Adds SYMB layer toggle to 'ä'

Closes #2

Also moves ctrl away from '-' and 'z' to the outer bottom corners
and removes redundant SYMB layer binds from there

* Adds mouse movement to right hand on ARRW layer

Closes #3

* Fix typoed keycodes

* planck qwerty nordic

* Update README.md

* Update README.md

* Implemented changes to planck layout requested by drashna

* Implemented changes to ergodox layout requested by drashna
