- Added the following hash functions:
- MD2 (`hashbase.MD2`)
- MD4 (`hashbase.MD4`)
- MD5 (`hashbase.MD5`)
- SHA-1 (`hashbase.SHA1`)
- CRC-8 (`hashbase.CRC8`)
- CRC-16 (`hashbase.CRC16`)
- Added unit tests for all hash functions
- Added an example file `examples/hash.py` that calls all the implemented hash functions
