feat: add initial idv types and config

Change description

• Added transactionId as optional to both withdrawal and deposit counterparty types
• Added the config type as discussed and additionally added the ability to pass an array or just the oAuth method to oAuth since we only have one right now

type IdentityVerificationConfig = {
    requiredMethod: IDV.SMS | IDV.EMAIL | IDV.VERIFF, // only one can be required
    oAuth: [ oAuth.COINBASE, oAuth.BINANCE ] | oAuth.COINBASE,
}

txOptions = {
    ...
    counterpartyAssist: {
        ...
        identityVerification: IdentityVerificationConfig;
    }
}
