Feature Request: Enhance FireDucks DataFrame with a native memory_usage() method.

Background: Currently, invoking memory_usage() on a FireDucks DataFrame defaults to pandas, leading to potential inaccuracies due to data copying between frameworks. This makes precise memory profiling challenging.

Proposed Solution: Develop an internal memory_usage() function within FireDucks to provide accurate memory consumption metrics without falling back on pandas.

Benefit: This feature will enable users to effectively monitor and optimize memory usage, especially when handling large datasets.
