More robust map generation classes

[FaronBracy]

The map generation in RogueSharp is very generic and not suitable for creating maps for real games. They were meant to be more of an example that could be expanded upon.

Consider including something similar to https://github.com/odedw/karcero in RogueSharp

I'm using Karcero with RogueSharp for map creation as it's pretty quick and flexible. I have to create the map using Karcero then map each Karcero cell back to a RogueSharp one. Not difficult but not sure how best to integrate it with RogueaSharp. Maybe a custom IMapCreationStrategy but then that would put a dependency on Karcero in RogueSharp and I don't think you really want that do you?

https://github.com/audinowho/RogueElements seems suitable. It even includes an example that shows integration with RogueSharp.
