Sessions open formatting amended

[americk0]

This just restructures the code a bit from #284 to match some of our code patterns like each function getting its own file and generalizing the code for parsing the account Id, alias, and role out of ALKS account strings to make it available for future work. I also swapped out the test data values with fake data to provide a little more security by obscurity

Big thanks to @KennyS-Cox for contributing the bulk of this work and also just for having the idea to do it in the first place. it really makes a difference in the readability of the output

closes #284
