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.
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.
