Deposit validation

[pavelkrolevets]

We need to double check deposit_file.json before it gets submitted to mainnet.

• added partial launchpad checks as we want to validate BLS signature using JS library before submitting the deposit.
• copy launchpad validation logic to golang

To run:

1. Build docker image

make docker-build-deposit-verify

2. Run docker container with 2 params: DEPOSIT_FILE_PATH=[path to deposit_file.json] and NETWORK_ENV_PATH=[path to network env (e.g. .env.holesky)]

make DEPOSIT_FILE_PATH=/home/pk/go/src/github.com/bloxapp/ssv-dkg/examples/deposit_data.json NETWORK_ENV_PATH=/home/pk/go/src/github.com/bloxapp/ssv-dkg/utils/deposit_verify/.env.holesky docker-deposit-verify
