Merge #126: Bump version to 0.19.0 and add CHANGELOG.md

ef9fd6b Bump version to 0.19.0 and add CHANGELOG.md (Steve Myers)

Pull request description:

  Besides bumping the version I've also added a simple changelog that list the PRs in this (0.19.0) and the prior (0.18.0) release. The main reason for this release is the bump of the rust-bitcoin version to 0.31.0 which is needed to upgrade dependent projects like bdk to also use rust-bitcoin 0.31.0.
