`API
base256.encode(buffer, num)
Pass a buffer and the number that needs to be encoded. The number will be encoded into that buffer.
base256.decode(buf, [offset])
Decode a number from a buffer. If an offset is passed as the second argument the buf should be decoded at that byte offset. The byte offset defaults to 0.
if the input yields a number that is out of range (-9007199254740991 to 9007199254740991).
- Throws TypeError if the input is of not correct type.
- Throws TypeError` if the output of decoded value of encoded buffer goes out of range -9007199254740991 to 9007199254740735. MIT
