Bulk add addresses (wallets, deployers) for projects in a network

[ccerv1]

A user should be able to specify a path to a CSV that assigns Ethereum addresses to project slugs and specifies whether they should be treated as wallets, deployers, or contracts.

The script should then lookup the address on Etherscan and return the following:

• EOA or contract
• If EOA, ENS name
• If contract, contract name
• Whether the entry already exists in OSS Directory or not

The script should output the file as a CSV with additional columns.

The script should also be able to ingest a processed CSV file and use it to make updates to OSS Directory project files.
