Simkin modular merge

[alfredsimkin]

made small modifications to schema.json to facilitate MIP files
wrapped sections of merge into functions
added an 'init' block
changed output folder from 'PMO' to 'finished_PMO_files'

I didn't wrap the functions into classes - I can do this if it would be helpful for consistency with the other pages (left it this way because I think readability is better, but maybe there are advantages to implementing as classes that I'm unfamiliar with - I'd like to learn more about it)

This looks so much neater, thanks Alfred!

When I build the app I am seeing these errors when the panel info and bioinformatics info aren't entered yet:

I'm also wondering if the check functions could be made into one more general function as they have the same pattern?

Also, what formatter are you using for your code? We seem to have some conflicts between what we're using
