aquatic-prime: Add an rough interface and a test for `sign()`

The `sign()` method will take a `HashMap` and return a signed digest of
the map.

Replicated the test from the Ruby edition of Aquatic Prime:
https://github.com/bdrister/AquaticPrime/blob/ce892dc/Source/Ruby/lib/aquaticprime.rb

Copied the expected values in after running the script.
