/**
 * Parses the Content-Range header into a structured object.
 * * Algorithm:
 * 1. Use a regular expression to capture the unit, start, end, and total size.
 * 2. The standard format is: <unit> <start>-<end>/<size> (e.g., "bytes 0-499/1000").
 * 3. Handle cases where the total size is unknown (indicated by '*').
 * 4. Convert the captured string values into numbers for easier processing.
 * * @param headerValue - The raw Content-Range header string
 * @returns A ContentRange object or null if the format is invalid
