 * FilesystemPersister persists channel data on disk, where each channel's
 * data is stored in a file named after its funding outpoint.
 * 
 * Warning: this module does the best it can with calls to persist data, but it
 * can only guarantee that the data is passed to the drive. It is up to the
 * drive manufacturers to do the actual persistence properly, which they often
 * don't (especially on consumer-grade hardware). Therefore, it is up to the
 * user to validate their entire storage stack, to ensure the writes are
 * persistent.
 * Corollary: especially when dealing with larger amounts of money, it is best
 * practice to have multiple channel data backups and not rely only on one
 * FilesystemPersister.
