Subject: [PATCH] feat: Add TsigAlgorithm enum and conversions

This commit adds the TsigAlgorithm enum, which represents the supported TSIG algorithms for DNS messages. It includes the HmacSha1 and HmacSha256 algorithms. The enum also provides conversions to and from strings for easy serialization and deserialization.
