Powerful little-endian base-128 encoding/decoding library for Python 3. Supports the following types: Unsigned LEB128; Signed LEB128; Unsigned LEB128 +1 ; Note. The LEB classes all inherit from int and have all the operations implemented. The type of the result from any int operation will always be the type of the lhs.

Encodes to and decodes from base128.
LEB128 or Little Endian Base 128 is a form of variable-length code compression used to store an arbitrarily large integer in a small number of bytes. LEB128 is used in the DWARF debug file format and the WebAssembly binary encoding for all integer literals.
If called from command line, this encodes a binary file into base128. If imported from python it provides a base128 class to do the same. An instance of base128 can be used to convert to and from base128 encoding. Encoding: The python package bitarray is used to insert a 0 bit every 8 bits of the data.
