Description

Before this PR, SQLIte prepared select statements are manually written using a format string, making it hard to get column values using a selected column name: there is no built-in way to track the column indices.
This PR implements a class to wrap SQLIte prepared select statement. It takes the column names to select, the table name to select from, and an "AND chaining" WHERE clause + an ORDER clause. This class maintains an internal mapping of the column indices so the caller can get column values by providing a column name.
The filters in the WHERE clause and the ORDER clause are formatted by the caller. The caller will take care of value binding using proper placeholders.

Validation performed

• Replaced the manually generated select statement by the new class in the existing unit test; using column names to get the column values directly.
• Added new unit test to cover filtering.
• Workflow passed.
