Change board width

[Not-A-Normal-Robot]

We already can change the board height, now we should be able to change the board width. The minos should zoom in/out accordingly i.e. 2x smaller board (in width) = 2x bigger minos. This should make Big Mode easy to implement.

It's in the todo-list, so just wait for it

it's not in the to-do list anymore, but hasn't been implemented. should we add a REMAKE tag on this?
