Implement Int128, Int256, and Int512 + their numeral literal suffixes

[SomeGuyWhoLovesCoding]

This pull request implements the logic of the 128-bit, 256-bit, and 512-bit integers. They are of course real integers, but right now you can't create those integers with decimal values directly as opposed to initializing 32-bit integer values.

No tests for those integer classes yet cause that causes me more stress.

I'm not sure if this is the right place to ask for help, the Issues tab might be more sufficient.

Actually I prefer a PR here because it's easier to reason about the code and see the failing tests, so I think this is a good initiative.

How come 14 tests failed?

The toString() function runs very slow, so I'm rewriting it.
