Create an apdu protocol version

[r4mmer]

Summary

The wallet has no way of knowing if a version of the app is compatible with it. We don't want users to update their wallets for every Ledger update, it should be up to the user even if it's recommended.

Current Solution

The current solution adopted is to choose an arbitrary Ledger app version that the wallet does not support and if we implement any breaking changes we should bump to that version.
For now the wallet assumes a bump on major will break compatibility but this is not ideal since if we would want to just patch anything on the protocol we'd need to do a major bump.

Proposed solution

Create a protocol version control that is separate from app version.
The protocol version can be a simple number or follow semantic versioning.
This protocol version should be how the wallet knows it can interact with the Ledger app as intended.
