/**
 * CommandHandler for the STOU command. Handler logic:
 * 
 * If the user has not logged in, then reply with 530 and terminate
 * Create new unique filename within the current directory
 * If the current user does not have write access to the named file, if it already exists, or else to its
 * parent directory, then reply with 553 and terminate
 * If the current user does not have execute access to the parent directory, then reply with 553 and terminate
 * Send an initial reply of 150
 * Read all available bytes from the data connection and write out to the unique file in the server file system
 * If file write/store fails, then reply with 553 and terminate
 * Send a final reply with 226, along with the new unique filename
