Feature Summary

CRC64 Algorithm Implementation

Feature Description

Hey, I'm replacing MD5 with CRC64 (security improvements) for content validation when PUTing a blob but I'm encountering a blocker. The CRC64 algorithm used by Azure Storage uses a custom CRC64 implementation of ECMA-182. This is accessible from the StorageCrc64HashAlgorithm class but not from your rust SDK. This would require interfacing with an implementation of the C# library.

Note: I've tried several CRC crates but none of them implement Azure's specific CRC64 algorithm.

Can you add an implementation of the Azure Storage CRC64 algorithm so it easily accessible from the azure_storage_blobs SDK?
