/**
* Projects the fields of an object based on a specified fields configuration.
* Supports inclusion (`1`) and exclusion (`0`) of specific fields. Creates a new object
* with the desired fields included or excluded, based on the configuration.
* @template T - The type of the object being projected.
* @param item - The original object to project fields from.
* @param fields - An object defining the fields to include (`1`) or exclude (`0`).
*   - Keys are the field names, and values are either `1` (include) or `0` (exclude).
* @returns A new object with the specified fields included or excluded.
*   - If all fields are set to `0`, the excluded fields are removed from the result.
*   - If fields are set to `1`, only the included fields are retained.
