Added type aliases for CHAR, FLOAT, and other data types to improve compatibility with Tableau.

Why it matters

This feature was created to address compatibility issues between ClickHouse and Tableau. By adding aliases for certain data types such as CHAR and FLOAT, it ensures that Tableau can correctly interpret and display data retrieved from ClickHouse, improving user experience and data integration workflows.

How to use it

Users do not need to perform any special actions or configurations. When querying ClickHouse from Tableau, the newly added type aliases automatically enable smoother data type recognition and compatibility. Simply connect Tableau to ClickHouse as usual and use SELECT queries to retrieve data.
