/**
 * Special method for variable length int (copied from lucene). Usually used for writing the length of a
 * collection/array/map In most of the cases the length can be represented in one byte (length < 127) so it saves 3
 * bytes/object
 *
 * @throws IOException If there is a low-level I/O error.
