Hardware Discovery

PyMoDAQ provides a shared, process-lifetime cache for enumerating hardware resources. Each backend is queried at most once per process; every plugin that imports from pymodaq_plugins_utils.hardware reuses the same cached result.

Both pyvisa and pyserial are optional dependencies. If a backend is not installed, the corresponding functions return empty lists silently — no exception is raised.
