NumListAdapter class

A NumListAdapter is a specialized BinaryListAdapter for handling lists of numeric values, encoding them as Base64 strings for storage.

This adapter uses a fixed byte size of 8 for each numeric element, allowing it to store both integer and floating-point numbers. It reads and writes numbers using big-endian byte order.
