Fix off-by-one bug in `hasLengthLessThan`

[JsseL]

This PR supersedes #53 by not just fixing the documentation, but also the incorrect error message. Also checked out hasLengthGreaterThan as @jfairbank suggested. Couldn't see a problem there, but did small renaming to make the tests easier to read.

Feel free to leave any comments or improvement ideas. I might be pretty busy, but I'll try to make required changes if possible.

And of course if this gets merged in, I'd be really happy if you could make a new release including the fix. :smile:

Thanks, @JsseL!

I'll try to get a release out as soon as possible. I have some other features that have been sitting in master, so I'll have to spend a little time finally documenting them for the release too.

[JsseL]

@jfairbank any chance you could make that release? I'd really like to get it in production as soon as possible. Thanks.

Hi, @JsseL.

Apologies for the delay. Things have been hectic for me, and I let this slip. I've published v1.2.0 with your fix.

[JsseL]

@jfairbank Awesome and I really appreciate that you found time to do the release. Thanks :+1:
