  12  * Lightning TLV uses a custom variable-length integer called `BigSize`. It is similar to Bitcoin's
  13  * variable-length integers except that it is serialized in big-endian instead of little-endian.
  14  *
  15  * Like Bitcoin's variable-length integer, it exhibits ambiguity in that certain values can be
  16  * encoded in several different ways, which we must check for at deserialization-time. Thus, if
  17  * you're looking for an example of a variable-length integer to use for your own project, move
  18  * along, this is a rather poor design.
