fastnumbers: Super-fast and clean conversions to numbers

fastnumbers is a Python C extension designed for super-fast and clean conversions of strings and other types to numbers. It provides convenient error handling, functions to check if an input can be converted, and drop-in replacements for built-in `int` and `float` that are often faster. The library is actively maintained, with version 5.1.1 being the latest stable release, and typically follows a regular release cadence as needed for bug fixes and improvements.
