Bump bitcoin and elements dep

When building without liquid feature there are warnings to use compute_txid but by fixing those the build with the liquid feature fails because there the methods is still just txid

I ran into a similar situation with deprecated methods when updating to rust-bitcoin v0.31 and ended up resolving them with some ebcompact traits that adds compatible methods to the rust-elements structs. A compute_txid->txid alias would fit there nicely.
