Failure to build dependent crates due to missing trait derivations

[tnull]

In 2bbfc28 all trait derivations except for Debug was removed. Now that this change shipped we're seeing some breakage downstream, i.e., rust-bitcoin 0.30.2 as we use it in rust-lightning fails with:

error[E0204]: the trait `std::marker::Copy` cannot be implemented for this type
   --> /Users/ero/.cargo/registry/src/index.crates.io-6f17d22bba15001f/bitcoin-0.30.2/src/blockdata/script/mod.rs:730:62

And locally I'm seeing the following for current master of rust-bitcoin:

Oh, I see this was already caught and is being worked on in #72.

[tnull]

Closing as bitcoinconsensus 0.20.2-0.6.0 just has been yanked.

Thanks @tnull, sorry for the problem, that was all me.
