python: Add find() to the Python API

This a mapping of uhd::device::find() into uhd.find() on the Python
side. The uhd::device is intentionally not mapped into Python (prefer
MultiUSRP or RfnocGraph instead), so the namespace is moved up one
level.

Example:
>>> import uhd
>>> # Now print the device args for all found B200s:
>>> for dev_args in uhd.find("type=b200")): print(dev_args.to_string())
