Closes: #2.
Libp2p supports multiple cryptographic curves, however we have currently only implented support for secp256k1.
This needs to be run with the compiler flag `libp2p_pki_schemes` set to `secp256k1`. If running the tests, this can be run like so: `nimble test —libp2p_pki_schemes=secp256k1` to put secp as the first supported crypto scheme.
Swap all instances of Record with SignedPeerRecord.
Allow for `SignedPeerRecord`s to be updated by updating the first multiaddress in the `PeerRecord`. This also increments the `seqNo` in the `PeerRecord` only if the address was actually updated.
Add CI workflow to run tests.
Add code coverage workflow that publishes results to CodeCov.
Add CI and coverage badges to README.
Bump asynctest to allow for `setupAll` and `teardownAll`.
Add local coverage nimble task.
Combine tests in to a testAll file.
