This adds both the recommended TypeScript checks, plus the recommended
TypeScript checks that require type checking. This latter addition
means that eslint essentially has to compile all of the TypeScript in
the project, causing it to be slower. This isn't much of a problem in
VS Code because there's a lot of caching being done, but it's clearly
slower when run on the commandline.
All of the errors are either fixed or suppressed. Some errors are
suppressed because fixing them would be too laborious for the little
value gained.
The eslint config is also slightly refactored to separate the strictly
TypeScript checks from the JavaScript checks.
* Refactor disk handling to allow disk processing to happen in a worker
* Type cleanup
* Convert format handlers to TypeScript
* Convert CFFA to TypeScript
* Typescriptify all of the UI peripherals
This converts the audio, gamepad, keyboard, printer, and tape
peripherals into Typescript. This is a pretty mechanical change.
It does fix issue #72, though.
* Add and that were missing
