Merge rust-bitcoin/rust-bitcoin#1694: release bitcoin_hashes 0.12

bfd401c96e bitcoin_hashes: add CHANgELOG (Andrew Poelstra)
d1b7b54e3a bump bitcoin-hashes version to 0.12 (Andrew Poelstra)

Pull request description:

  It was a little tricky to bump the version number because of https://github.com/rust-bitcoin/rust-bitcoin/issues/1553. There are a couple other things I considered trying, which maybe we'll do for future releases, but I believe this works for now.

  Maybe should wait for #1111.
