LEB128 (Little Endian Base 128) Encoder/Decoder

The `leb128` Python library provides functionality for encoding and decoding integers using the LEB128 (Little Endian Base 128) variable-length compression format. This format is commonly used in contexts like the DWARF debug file format and WebAssembly binary encoding for integer literals. The library supports both unsigned and signed LEB128 operations. It is currently at version 1.0.9 and appears to have a stable, though infrequent, release cadence, with the latest release in January 2026.
