Implement noisy float

[Libbum]

• [x] config
• [x] potential
• [x] grid
• [x] input
• [x] output
• [x] verify current tests still pass Should hopefully help identify issues in #31 and #48

[Libbum]

This has probably got it done. A few things are still raw floats and it could probably be implemented a little cleaner.

• Should benchmark and see if the claims about the zero overhead is true.
• Unsure if this is something that should be merged, but maybe just used to debug the issues cited above, the solutions of which can be merged in without all this noise?

I think merging is fine since it isn't all that different. Times? Don't seem to be an issue. Bugs? They're not reproducing in this branch?

Will keep #31 and #48 open and reinvestigate them with this setup.
