The `hashes::error::FromSliceError` error is only returned from
`from_slice`. We attempted to deprecate this function but it seems we
only did half a job at it.
- deprecate _all_ instances of the method/function
- deprecate the error type
Currently in order to release `hashes v1.0` we need to 1.0 `io` as well.
For multiple reasons, many out of our control, the `io` crate may not
stabalise any time soon.
Instead we can invert the dependency between the two crates.
This is an ingenious idea, props to Kixunil for coming up with it.
Notes
- `io` does not currently re-export the `hashes` crate.
- This work highlights that we cannot call `hash_reader` on a siphash.
- The `Hmac::hash_reader` uses the default key which may not be obvious.

In preparation for removing a bunch of macros move all the modules to
`<mod>/mod.rs`.
Do so by running the following shell:
```bash
for mod in hash160 ripemd160 sha1 sha256 sha256d sha256t \
sha384 sha512 sha512_256 siphash24 hkdf hmac; do
mkdir $mod
mv "$mod.rs" "$mod/mod.rs"
done
```
Internal change only.
