An interface extendingList<String>used for repeated string fields to provide optional
access to the data as a list of ByteStrings. The underlying implementation stores values as
either ByteStrings or Strings (seeLazyStringArrayList) depending on how the value was
initialized or last read, and it is often more efficient to deal with lists of ByteStrings when
handling protos that have been deserialized from bytes.
