Adding generation of inside(center)-out maze pattern

[RasaKh]

Hi there and thanks for this super useful code.
Would it be possible for you to add support for circular (or any) maze shapes to start/end in the center of the maze and end/start somewhere on the border?

Wouldn't this just mean closing one of the two openings on the outside? How do we mark the centre as the "target"? Any suggestions?

I'm not too sure honestly. I just saw this capability in a website (https://www.mazegenerator.net/ Circular mode) and thought it'd be a nice addition to this opensource project. Maybe it's generated from inside out rather than outside in.
