Subject: [PATCH] Use precision when formatting core::hash::Hasher

It seems the `core::hash::Hasher` supports precision as well as width
formatting but defaults to displaying as an integer.

To be uniform with our usage of `hashes::sha256::Hash` type (and
unsurprising to the reader) use the precision formatting parameter.

Note this does not change the output, the unit test is not touched.
