Implement CassandraDMLGenerator for Generating Cassandra-Specific DML Statements

Description:
This PR introduces the CassandraDMLGenerator class, which implements the IDMLGenerator interface to handle the generation of Cassandra-specific Data Manipulation Language (DML) statements. The primary features and enhancements included in this implementation are as follows:

Key Features:

• DML Generation Support:
  • Implements the getDMLStatement method to construct Cassandra-compatible DML statements (e.g., INSERT, UPDATE, DELETE, and UPSERT).
  • Validates and maps input data against the schema to ensure correct column names and data types.
• Flexible Data Handling:
  • Supports primary key and non-primary key handling for both insert and update operations.
  • Includes mechanisms for handling complex data types and converting them to Cassandra-compatible formats.
• Timestamp Management:
  • Adds support for appending USING TIMESTAMP in queries, leveraging precise control over data consistency in Cassandra.
• Robust Error Handling:
  • Includes logging for unknown options, invalid data types, and schema mismatches.
  • Throws appropriate exceptions for unsupported configurations and invalid inputs.
