v2.0

fixes:

• all the cut methods
  yeah, that was like... the library itself, and it wasn't working
• the rect debug representation
  previously it was Rect: X(minX, minY), Y(maxX, maxY), which didn't align with Rect:unpack(), so X and Y were changed to min and max respectively

additions:

• (QOL) camelCase versions of all the methods
• improve unknown side errors in the Rect:get/add/cut methods

wrote tests (adapted from the Rust implementation)
