feat(sdk-coin-vet): address and wallet creation

[mohitkh7]

Ticket: COIN-4185

This pull request introduces several enhancements and new features to the sdk-coin-vet module, including dependency updates, implementation of previously unimplemented methods, and additional test cases to ensure functionality. These changes improve the module's utility and robustness.

Dependency Updates:

• Added new dependencies: @bitgo/abstract-eth, @bitgo/secp256k1, and crypto to support cryptographic operations and Ethereum-related functionality. (modules/sdk-coin-vet/package.json, modules/sdk-coin-vet/package.jsonL44-R46)

Feature Implementations:

• Implemented the isValidAddress method in Utils to validate Ethereum-style addresses using a regular expression. (modules/sdk-coin-vet/src/lib/utils.ts, modules/sdk-coin-vet/src/lib/utils.tsL5-R5)
• Updated the Vet class to:
  • Validate wallet addresses with the isWalletAddress method, throwing an InvalidAddressError for invalid addresses. (modules/sdk-coin-vet/src/vet.ts, modules/sdk-coin-vet/src/vet.tsL81-R90)
  • Implement the generateKeyPair method to create extended key pairs using bip32 and randomBytes. (modules/sdk-coin-vet/src/vet.ts, modules/sdk-coin-vet/src/vet.tsL97-R127)
  • Add the isValidPub method to validate public keys using EthKeyPair. (modules/sdk-coin-vet/src/vet.ts, modules/sdk-coin-vet/src/vet.tsL97-R127)

Test Enhancements:

• Added unit tests for the isValidAddress method to verify its correctness with various valid and invalid Ethereum-style addresses. (modules/sdk-coin-vet/test/unit/vet.ts, modules/sdk-coin-vet/test/unit/vet.tsR28-R36)
