Reorg-resistance for the Ethereum backend and support for external Watchtowers.

Added

• ✨ Ethereum backend: Reorg resistance #19: The Ethereum backend now lets the user specify after how many blocks a transaction or an event should be considered confirmed.
• ✨ Watcher interface #172: The watcher logic is now injectable. The adjudicator takes a watcher instance as a setup parameter. This enables using remote watcher services. A local watcher implementation is provided.

Changed

• ⬆️ Update go to v1.17 and go-ethereum to v1.10.12.
• ✅ Extend support for additional blockchain backends by revising the generic tests (e.g., #225, #227, #228).
• 🚸 Improve usability (e.g., #124, #144, #196, #204, #240).

Fixed

• 🐛 Improve stability (e.g., #129, #134, #148, #191, #207, #218).
