Make a few sorts unique so that even bad data produces good usable output

[fredcooke]

Fixes #89

Enhancement to this could be to warn user that it's bad if input list size not equal output list size or fix it if it's bad straight up seeing as we modify it without explicit permission anyway.

Build failure is from shellcheck on osx because brew gives you the latest and is complaining about line 69 of branchout-groups (pre-existing code) with this link:

https://github.com/koalaman/shellcheck/wiki/SC2295

However it doesn't really cover the exact case and it seems to be either a false positive or my syntax highlighting is broken or it's not possible to do what you are doing AND satisfy shellcheck or something. Full text:

@stickycode there's now two failures on mac - both new shellcheck checks - Linux passing. Please merge if you're happy. Note I'm not happy but I think it's a step in the right direction, just more required to be good on the status front.

[fredcooke]

@stickycode I can't override the status requirement so feel free to merge on my behalf and generate a new release of it if you want.

It wasn't an override in the end, on refresh, not sure what changed.
