bump bdk message signer

[aagbotemi]

Description

Migrates the BIP-322 message signing integration from bdk_bip322 0.1.0 to bdk_message_signer 0.2.0, and bumps bdk_wallet from 2.4.0 to 3.1.0.

Notes to the reviewers

The bdk_wallet bump is included here out of necessity, bdk_message_signer 0.2.0 implements its signing traits for bdk_wallet 3.x's Wallet type. With the CLI on 2.4.0, cargo resolves two incompatible copies of bdk_wallet and the sign/verify methods don't exist on the CLI's wallet (as at the point of creating this PR), so the feature cannot compile without the bump.

Changelog notice

• Replace the bdk_bip322 dependency with bdk_message_signer 0.2.0
• Bump bdk_wallet to 3.1.0 and fix the resulting breakage.
