* Refactor disk handling to allow disk processing to happen in a worker
* Type cleanup
* Convert format handlers to TypeScript
* Convert CFFA to TypeScript
* Switch modules to `esnext` to allow `webpack` to see import statements
* Pass rom names into Apple2 class
* Move ROMs into `system` and `character` directories to allow webpack bundle appropriate ROMs.
* Wait for ROMs to load before completing initialization.
This is mostly a mechanical change; there are still lots of things
about `ui/apple2` that could be improved. The change also converts a
few dependencies of `ui/apple2`, like `applesoft/compiler`.
Besides the straight conversions, some other packages have changes to
make all of the typing work out.
Lastly, `@types/micromodal` has been added as a development
dependency.
