What does this Pull Request accomplish?

This fixes the service_type, connects_to_bus_type and provides_bus_type filter options by specifying them as UnsignedIntProperty instead of IntProperty.

Why should this Pull Request be merged?

This PR address #67

The Filter object uses NISysCfgSetFilterPropertyWithType to set values. This requires knowledge of the backing type to retrieve the value.

What testing has been done?

Ran unit tests; all tests passed.

Checked that PXI devices could be found with

import nisyscfg
session = nisyscfg.Session()
hw_filter = session.create_filter()
hw_filter.connects_to_bus_type = nisyscfg.enums.BusType.PCI_PXI
hw = list(session.find_hardware(hw_filter))
print(hw)
