Refactor to the moon

Summary

This PR does a few things, but there are 2 main highlights:

1) Utilize a state management library, recoil, to control the simple states of the app from a top-level. This avoids the need to pass any props to components, and avoids the need for the contexts to require every state variable used by the app. You can read the docs to read more about it, but here is the basic idea:

• An atom represents a piece of state in the application. I have added atoms for the measure and patient bundle content, dropdowns, the output type, the calculation options, and the measurement period.
• A selector represents a piece of derived state. I.e. it can take the value of an atom and use it to derive a different piece of state. An example of this is that the content of the connectathon patient dropdowns depend on the content of the connectathon measure dropdown. The latter is an atom, and the former is a selector for that atom.
• Whenever you need to access these atoms, you can use a hook very similar to useState. E.g.

  const [outputType, setOutputType] = useRecoilState(outputTypeState) // outputTypeState is an atom

2) Re-organize the component structure of the app. The folders are now segmented more and clearly labeled for what their purpose is. Here is a diagram of the components

Other Changes

• Make use of react suspense API to have loading spinners for the dropdowns when the options are loading
• Only include connectathon dropdowns for now (see details)
• Added some styling to not have a file upload push down the screen
• Centered some buttons
• Changed the download button to an icon
• Increased default collapsable level of react json view
• Removed some erroneous grids
• Added only results to json view, don't include debug output
• Disabled dropdowns when file is already uploaded

New Behavior

Only new behavior is the loading icons, the rest of the functionality is the same

Testing guidance

Test all features

Apparently this bundle has no entires lol. We should fail more safely in this case, but that's in fqm-execution land
