 * File size contract enabling interoperability with external file size libraries.
 * Provides a standard way to convert any file size representation to bytes.
 *
 * Allows this library to work with external size libraries without direct dependencies:
 * - Byte wrapper objects
 * - Kilobyte/Megabyte/Gigabyte representations
 * - Custom file size classes
 *
 * Implementers need only provide one method: convert their file size format to bytes.
 *
 * Usage:
 * 1. Implement IFileSize on your file size class by computing the TO_BYTES method
 * 2. Pass instances to any daiso-core function accepting IFileSize
 * 3. The library will call the method to get byte values for size calculations
