update windows-sys to 0.61 or earlier

[sendittothenewts]

windows-sys is a frequent source of duplicate dependencies. Widening the range of allowed versions gives downstream crates a fighting chance of being able to select one unique version of it.

[sendittothenewts]

I have of course tested this. cargo test passes with both windows-sys 0.61.0 and 0.28.0 (and fails to compile on windows-sys 0.27).

I like this idea. Could you add some sort of test to .github/workflows/ci.yml to make sure we test this bound going forward? (Also I just pushed the bump to 0.61, so you'll need to rebase. Edit: I just did it here.)

[sendittothenewts]

Ok, I've added the test, and it looks to be passing. I considered making that Windows-only, but then it occurred to me that testing the minimum libc crate might also be reasonable.

@oconnor663 Are you still interested in merging this? If so, a release including this pull some time in the next couple of weeks would be convenient.

[oconnor663]

Thanks for the reminder. I'll rebase this by hand and push a release.

[oconnor663]

Released along with #38 as v1.2.3.

Thanks! This has cleaned up my deps nicely.
