[Suggestion] Eraser Piece Graphic Set

[GigaLem]

This can be applied to the legacy and community editions to NL, Basically a series of blank white shapes, curves and such of varying sizes for the purpose of erasing and grouping. I was a bit hesitant to suggest it but Namida didn't mind the idea when I spoke about it on Discord.

While the System test set has some pieces that can fit, im talking Concave and Convex curves, S pen slopes, Right Angle slopes of varying degrees even resizable pieces for measuring or mass erasing.

I actually think this would be very useful to have. It doesn't necesserially have to be official - while it might be a bit different in purpose from other styles out there, it's still a useful tool for building levels and thus I'd see it as absolutely valid to submit as a style, so if WillLem doesn't want to take this on as an official supported thing, you'd be more than welcome to just make it as "gigalem_erasers". (Personally, if I were still developing NL, I'd simply accept it as just "erasers" if you wanted, but that's WillLem's / the community's decision at this point.)
