Add Fake Bitcoin Address and Transaction Hash Generation

Description

This pull request adds support for generating fake Bitcoin addresses and transaction hashes within the Java Faker library. It includes:

• Bitcoin Address Generation:

  • Implemented methods to generate fake Bitcoin addresses for the main network (address()) and the test network (testnetAddress()).
  • Addresses are generated using Base58Check encoding with network-specific version bytes (0 for mainnet, 111 for testnet), following Bitcoin's address format conventions.
  • For more details on these version bytes and their corresponding address prefixes, refer to the Bitcoin Wiki - List of address prefixes.

• Transaction Hash Generation:

  • Added a method (generateTransactionHash()) to create random 64-character hexadecimal strings simulating Bitcoin transaction hashes.
  • The method uses SHA-256 hashing for generating the transaction hash format.

Motivation

This addition allows Java Faker to generate realistic data related to Bitcoin transactions, enhancing the library’s utility for testing cryptocurrency-related applications.

Testing

• Added unit tests to verify:
  • Correct format and prefix of mainnet and testnet addresses.
  • Address length within the expected range (26 to 35 characters).
  • Validity of generated transaction hashes as 64-character hexadecimal strings.

Notes

Please let me know if any adjustments are needed, or if further tests and documentation updates are required.
