Anchors Integration tests

[benthecarman]

todos:

• fix lnd crate to be usable
• fix cargo workspace stuff
• more test cases

[benthecarman]

Have tests for all the different cases working locally.

Getting the tests mergeable is another story however, things don't play well with the wasm stuff

[AnthonyRonning]

Do you want to split out the commits then? Have the integration tests seperate from the code changes that can be merged in?

[benthecarman]

That's what I'm doing, testing with cln locally now
