## Summary
Moves the bridge-unlock memo out of `astria-bridge-withdrawer` and into
`astria-core`.

## Background
This type needs to be publicly readable for `astria-cli` and other
consumers.

## Changes
- Move the `BridgeUnlockMemo` type to `astria_core::bridge`
- Change the public memo fields from ethers types to native Rust types
- Encode the contained transaction hash as base64
- Provide snapshot tests

## Testing
bridge-withdrawer tests still pass.

## Breaking Changelist
The transaction hash field in the memo being encoded as `base64` is a
breaking change for bridge-withdrawer.
