Upgrade secp to 0.31.1

Upgrade to the latest released version of `rust-secp256k1`. Do just
the build errors. Note one deprecated call to `thread_rng()` is added,
I'm not sure why this line was building before but anyways the `rand`
stuff will be done next.

The short version

What changed, and why it matters

This commit updates the underlying cryptographic library (rust-secp256k1) from version 0.30.0 to 0.31.1 and makes the small code changes needed to keep the project compiling. The newer library version may include its own bug fixes, but the commit itself is a routine dependency upgrade rather than a direct fix for a known security flaw in rust-bitcoin.

Recommended action

Review the rust-secp256k1 0.31.1 release notes for any security advisories, verify the lockfile changes do not introduce unexpected transitive dependencies, and run the full test suite to ensure cryptographic behavior is unchanged.

Security signals we found

01

Dependency upgrade of core cryptographic library (secp256k1 0.30.0 -> 0.31.1)

02

Transitive dependency updates including rand, getrandom, wasi

03

API migration from reference to value passing for Message/SecretKey

04

No explicit security fix or CVE reference in commit message or diff

Split Address into an extension trait

This commit is a routine code reorganization in the rust-bitcoin library. It moves the `Address::from_script` method out of the main `Address` type into a new 'extension trait' called `AddressExt`. The actual logic of the function is copie…
