Support for 21 x 21 Sunday-Sized Puzzles

[eljobe]

I really like the idea and the interface for this tool. How difficult would it be to support puzzles of a different size. Say a 21 X 21?

I'm an okay programmer by trade. Maybe I could make a pull request if you can point me in the right direction.

Just change const DEFAULT_SIZE = 15; to your prefered value in cross.js. Or Crossword(12, 23) at let xw = new Crossword(); for non-squared 12×23 crossword (in cross.js too).
