Chord display components

[mickmister]

Brought over chord display components from jam-app project https://github.com/jamtools/jam-app/blob/master/src/components/progression_view/progression_view.tsx

Next steps are to get the current progression showing in the view

To build and run webapp:

cd webapp
npm i
npm run local

Then navigate to http://localhost:1234

This runs Jam Tools in "local mode", which makes it so the whole program runs in the browser without any server. The browser's MIDI API interacts with the MIDI instruments directly. This is the easiest way to set up.

Alternatively, you can run with a server, which is typically how you would run Jam Tools in a group setting, at least with how the app currently works. To run with a server:

cd webapp
npm i
npm run dev

cd server
npm i
npm run dev
