ec06028f63 hashes: Make hex dependency optional (Tobin C. Harding)
9dce0b4b8c Remove hex string trait bounds from GeneralHash (Tobin C. Harding)
766f498b33 Pull serde stuff out of impl_bytelike_traits macro (Tobin C. Harding)
Pull request description:
This is done in 3 parts:
1. Pull the `serde` stuff out of `impl_bytelike_traits` to fix the bug described here: https://github.com/rust-bitcoin/rust-bitcoin/issues/2654#issuecomment-2470716693
2. Prepare the `hashes` trait by removing string/hex trait bounds from `GeneralHash` and also pull the hex/string stuff out of `impl_bytelike_traits`
3. Make hex optional, including adding custom debug logic when `hex` feature is not enabled
Patch 3 is tested in `hashes/embedded`, by the new `debug` unit test, and there is a `Midstate` unit test as well that covers the `Debug` impl.
