Add a few test cases for non-byte-aligned raw data keys

Browse Source 
Add tests for derivation.

Test both 7 bits and 9 bits, in case the implementation truncated the
bit size down and 7 was rejected as 0 rather than because it isn't a
multiple of 8.

There is no corresponding test for import because import determines
the key size from the key data, which is always a whole number of bytes.
