Dear Maintainer, Python 3.12 changed recursion mechanism [1]
sys.setrecursionlimit() and sys.getrecursionlimit(). The recursion limit now applies only to Python code. Builtin functions do not use the recursion limit, but are protected by a different mechanism that prevents recursion from causing a virtual machine crash. so increasing recursion limit as py-ubjson did [2] makes your package buildable.
