Properties resolution_digits and input_resistance incorrect

[cthomas97]

resolution_digits and input_resistance properties are linked to enums which then sets int32 type.
These two functions require real64 types.
session.py line 304 should be input_resistance = AttributeViReal64(1150029)
and line 531 should be resolution_digits = AttributeViReal64(1250003)

Setting properties raises TypeErrors.
