Describe the bug

Steps to reproduce:

1. Running a local node with anvil
2. Deploying a contract with arbitrary storage writes
3. Getting the proof for one of the storage slots as cast proof <contract> <slot>

The returning account and storage proof array elements have a wrong RLP encoding which cannot be decoded.
