document results of calling functions with negative bases

[matthewleon]

Example: toBase will accept negative Ints as parameters. It would be nice for comments to address the behavior in this case.

There are multiple options here, I guess:

1. simply document the current behavior (I have no idea what happens)

2. clamp the integer argument to the maximum range (2..36?)

3. Follow a similar approach as in Add conversions to a different base, fixes #17, fixes #18 purescript/purescript-integers#19 and only allow certain arguments.

for 1, from what I've seen, weird things happen :)

I'd say adopt 2 and offer 3 as an alternative API. The perf hit should be negligible considering the other things that this lib does.

Agreed - thanks!

Actually, the underlying lib does handle weird bases, and documents what happens with them. Probably worth just repeating that documentation.
