Pull request description:

The 0.32.0-beta line was yanked from crates.io when 0.33.0 was released.

Also `XOnlyPublicKey::serialize` was deprecated for `to_byte_array` and `secp256k1::Keypair::from_seckey_byte_array` became
`from_secret_bytes`.

The short version

What changed, and why it matters

This commit updates the project's cryptographic library dependency from a yanked beta version to a stable release. A 'yanked' package is one the authors have removed from public download, usually because it has problems. The change itself is a routine maintenance update, not a fix for a known active attack. It keeps the project buildable for anyone downloading it fresh, but the commit message does not describe any specific security vulnerability in the old version.

Recommended action

Treat as a normal dependency maintenance merge. Verify that CI passes with secp256k1 0.33.0 and that downstream consumers are not pinned to the yanked 0.32.0-beta.2 release. No emergency response is warranted based on the supplied materials.
