protocol utils: try known keys first

[felix-albrecht]

This PR implements the search for known keys, as suggested by @ThiefMaster (could close #34)
The arrays should contain all the keys that have been dug up so far :)

Also adds arguments for dumping EEPROM and memory.

Hi, thanks for the PR. That looks very nice.

I've decided to change the target branch to master, which might have messed up some of your commits (sorry about that).

Could you also move the CLI tools to src/bin/ as part of your PR? I think that would make sense since they're not really examples anymore.

[felix-albrecht]

I moved the examples to src/bin and added clap as an optional dependency. The CI pipeline runs fine on my fork.
Sorry for the many commits, I had to rebase two times because I hadn't set up signing keys for commits before.

(if the maintainer is happy there is no reason to listen to me but I would think that ideally the access codes would be collected from all existing implementations dynamically instead of hardcoding separately and needing to keep in sync. But that might require bigger refactor I guess)

[medusalix]

I think that's fine for now. I plan on refactoring the device connection/initialization anyway once I implement baud rate switching. So that can wait until then.

@felix-albrecht Could you squash your comments? That would make it a bit easier to review for me.

I just removed one x in the print statement for the Software ID, to have it in decimal :)
