Complete Implementation of Units in get_data()'s

[n-beckage]

Set the name attributes in the final nested series return by get_data()'s to contain the units for the respective variable. This is already done for aorc_ob.py and lcd_ob.py but needs to be implemented in the rest of the data acquisition modules. Use utils.add_units() to achieve this. Said function requires var_dict, a dictionary of user_var_names : units. Units should be directly inferred from raw dataset where possible as opposed to being manually set.
