clipboard: add qsv clipboard command for clipboard input/output

[rzmk]

Adds qsv clipboard command to allow providing input from clipboard and saving output to clipboard. Resolves #1561.

This also adds the arboard crate. I recommend trying the ignored test on macOS/Linux to ensure it works as intended (copy the non-Windows stats string then run the test).

Improvement idea:

• Optionally provide a file path to either write to it from clipboard or save its contents to clipboard (and tests for these scenarios)

Awesome stuff @rzmk!
