919da441746bf220c011fe593bfaf80256071674 consensus_encoding: Bump version to 1.2.0 (Nick Johnson)

Pull request description:

Release the new lower level encoder/decoder driver interfaces. There should only be additions to the API in this release.

I have a [rust-psbt branch](https://git.rust-bitcoin.org/rust-bitcoin/rust-psbt/pulls/208) showing off the new interfaces end to end.

The short version

What changed, and why it matters

This commit is a routine version bump for the bitcoin-consensus-encoding crate from 1.1.0 to 1.2.0. It only updates version numbers in lock files, the crate's Cargo.toml, and the changelog. There are no code changes, bug fixes, or security patches in the diff.

Recommended action

No security action needed. Treat as a normal release bookkeeping commit.

Security signals we found

No strong security signals were identified.

Technical analysis

Evidence from the diff

The commit merges a release tracking PR. The diff consists entirely of updating the package version string from ‘1.1.0’ to ‘1.2.0’ across Cargo.lock files and consensus_encoding/Cargo.toml, plus a changelog entry describing new lower-level encoder/decoder interfaces added in prior PRs. No source code is modified in this commit.
