Remove sha256t_hash_newtype macro 

Since commit `commit 275adc6c335a4326699cfbd444949e1725864ea1` on
`bitcoin_hashes` we have the identical implementation of the macro
`sha256t1_hash_newtype` in this crate and in `bitcoin_hashes`.

Remove the `sha256t_hash_newtype` macro from this crate in favour of the
one in `bitcoin_hashes`.
