   Follow up to #883

   Advantages:

   • 100% test coverage + CI set up
   • smaller tests that strictly address properties of the specs
   • documentation
   • vectors.json identical to Trezor’s + tests for seed verification with a passphrase
   • idiomatic code, no compilation warnings, no unnecessary conversions to strings containing binary numbers
   • flexible interface, e.g. works with raw binaries as well as hex-encoded
   • does not output 1.5M of text when running tests
   • does not confuse entropy with a private key
   • no commented out code
   • descriptive commit log @prusnak let me know if you’d like me to squash the commits
