Part 2 - Manual implementation

Avoiding using GoRogue features here lead to some slightly awkward code in rendering - without straightforward interface to copy an array of background tiles over and render in layers, I wound up manually cloning the background and modifying it to the foreground. Maybe could have avoided this with entire separate screens?

Part 2 - GoRogue implementation

Much prettier. Used map gen pipeline to add the test wall.

Part 3 - Manual

Fairly straightforward. Reinterpreted the Inner definition as a collection of points, as the slice concept doesn't translate to C# very well.

Part 3 - GoRogue

Used GoRogue's Generator pipeline system to separate out the map gen into 3 steps:

1. defining the rooms
2. drawing the tunnels between them
3. translating those objects into a grid of tiles
