LEB128 Encoding and Decoding Utilities

The `leb` Node.js module provides a suite of utility functions for encoding and decoding integers using the LEB128 (Little-Endian Base 128) variable-length representation format. It supports both signed and unsigned values, with options for 32-bit integers, 64-bit integers (which return a `lossy` flag due to JavaScript's number precision limitations), and arbitrary-length buffer representations. Currently at `v1.0.0`, the package was recently resurrected and aims to provide a reliable, dependency-free solution for LEB128, a format notably used in the DWARF 3 debugging format and Android's DEX file format. The package maintains a stable API with no breaking changes in its recent major release and focuses on direct encoding/decoding operations for binary data within Node.js environments.
