Reduce repetition in data source config validation

[Sukh-P]

Detailed Description

At the moment in the open_and_return_data_pipes function there is some repetition of code since there are repeated checks on each data source which checks a bool, an input configuration is not none and filepath/filename is not an empty string, see here for an example

Possible Implementation

Write a helper function which does these checks given some inputs to reduce repeated code

Hi, can I take this issue? I'm thinking about making a nested helper function to reduce the repetition.

@Sukh-P, yeah sorry I don't think I have the time to work on this right now so best to reassign to make way for someone who can. Thanks.
