Merge rust-bitcoin#4471: Change rustdoc tag from compile_fail to ignore

f5b716b Change rustdoc tag from compile_fail to ignore (Jamil Lambert, PhD)

Pull request description:

  The example code is supposed to fail to compile, but if it does run it panics. This somehow confuses the compiler so that either the `compile_fail` tag compiles but causes a lint warning about the panic or using `should_panic` fails to compile.

  Change the tag to `ignore`

  Closes rust-bitcoin#4259
