Merge #128: ci: add test with MSRV 1.63.0

4b42108 ci: add test with MSRV 1.63.0 (Steve Myers)

Pull request description:

  Since the main BDK crates are changing to MSRV 1.63.0 as is LDK the CI for this project should also have an MSRV and test against it in CI.

  Also rustc 1.63 is the version shipped with the current debian stable (bookworm): https://packages.debian.org/stable/rust/rustc
