[feat] Add CRC checksum calculation support

[das-Abroxas]

Goal

Implement CRC checksum calculation support to enable data integrity validation for S3 uploads using CRC32, CRC32C, and CRC64NVME algorithms.

Workplan

1. Create CrcTransformer that supports at least CRC32, CRC32C, and CRC64NVME checksum calculation
2. Write unit tests for all three CRC algorithms

Definition of Done

• CrcTransformer implemented with support for CRC32, CRC32C, and CRC64NVME
• Unit tests pass for CRC32 algorithm
• Unit tests pass for CRC32C algorithm
• Unit tests pass for CRC64NVME algorithm

Test Concept

Unit tests for each of the three CRC algorithms (CRC32, CRC32C, CRC64NVME) to verify correct checksum calculation. Tests should validate that the transformer produces expected checksum values for known input data.
