Revised Anvil test pipeline + add transferETH, transferERC20, signMessage methods

[bjfresh]

Previously, we relied on a custom wagmi renderer and e2e testing. Here we run transactions more directly against anvil by spinning it up using the viem/anvil package on a local RPC endpoint.

The endpoint invokes a walletClient, which is then used to create new signers for ethers5 and ethers6 using an adaptor.

Each of the tests is run against all 3 signing implementations.

Current test sequence:

✓ can mint 2 Zora 721 NFTs into Anvil wallet #0
✓ can transfer one of the minted NFTs to the TBA
✓ can createAccount
✓ can getAccount
✓ can transfer ETH to the TBA
✓ can executeCall with the TBA
✓ can transferETH with the TBA
✓ can transferNFT with the TBA
✓ can mint 2 Zora 721 NFTs with the TBA
✓ can transferERC20 with the TBA
✓ can use a custom publicClient RPC URL
✓ can sign a message
✓ can sign a hexified message
✓ can sign a Uint8Array message as raw
✓ throws when viem incorrectly receives an ArrayLike message for signing
✓ throws when viem incorrectly receives an Uint8Array message for signing

Additional changes:

• adds new transferETH, transferERC20, + signMessage methods
• removes simulateContract calls within methods and simply uses executeCall (mmmmm, dogfood! 🦴)
• enables users to specify a custom publicClient or publicClientRPCUrl
• adds Prettify type so that fields from types are cleanly exposed in VSCode
• moves prettier/eslint config to YAML so it's less finicky (read: actually works)
• rolls prettier back to 2.8.8 due to eslint-prettier conflict in newer versions
• bumps viem deps
• moves params types into separate file
• adds transaction debug helper function
• fixes the name of SegmentedERC6551Bytecode type (oops, was SegmentedERC1155Bytecode 😬)
