Does what it says on the tin, using [MaybeUninit<u16>; N] instead of [0u16; N]. These buffers seem to be around 8kb, which is big enough that this is likely to be a very nice perf boost to stdio-heavy windows code.

(Note: this PR also has a commit that adds windows to CI, but as it mentions I'll revert that after it comes out green -- I can only do a check build on the machine I'm typing this on)
