Lazy load ROMs (#81)
* 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.

Convert cards/disk2.js to Typescript (#54)
* Convert `cards/disk2.js` to Typescript

This is mostly a straightforward conversion of `cards/disk2.js` to
Typescript, with the following exceptions:

*   `setState()` did not restore the drive light state correctly
    because the callback was called with the old `on` value.

*   `setPhase()` did not work for WOZ images.

*   `getBinary()` did not work for `nib` files.

*   `getBase64()` did not work for `nib` files and maybe didn't work
    right at all.

Even with these fixes, local storage still doesn't work correctly.

I have also added several TODOs where methods don't support WOZ disks.

* Convert most uses of `memory` to `Uint8Array`

There are many places in the existing code where we use `Uint8Array`
directly. This change merely makes the `memory` type equivalent to
`Uint8Array`.

This change also changes most ROM data to be read-only in Typescript
to ensure that it is not modified by mistake. This can't be done just
by applying `as const` to the declaration because `Uint8Array`s are
can not be expressed as literals. Instead, we create a new type,
`ReadonlyUint8Array` that drops the mutation methods and makes indexed
access read-only.

See
https://www.growingwiththeweb.com/2020/10/typescript-readonly-typed-arrays.html
for details.

* Tighten types and document `disk2.ts`

While trying to understand the Disk ][ emulation, I tighted the types
and documented the parts that I could, including references to other
sources, like _Understanding the Apple //e_ by Jim Sather.

The one functional change is the addition of the P6 ROM of DOS 3.2 and
earlier. This is automatically selected if the card is initialized for
13 sector disks.

More typescript conversion (#46)
* Convert js/ram to a class

* Convert js/mmu to Typescript

* Convert js/apple2io to Typescript

* Convert js/canvas to Typescript

* Use new types in js/mmu

* Rename js/symbols.js to js/symbols.ts

* Remove the difference between readPages and writePages

As @whscullin said in PR #38, there's no need to have both readable
and writable pages since all implementations are currently both. This
change combines them into `Page`. Likewise, `PageHandler` now extends
`Page`.

`Apple2IO` now implements `PageHandler`. This caught a bug where `end`
had been renamed `endend` by mistake.

There are a few other formatting changes as well.

* Convert js/apple2 to Typescript

* Convert js/prefs to Typescript

* Convert all of the ROMs in js/roms to Typescript

Now all of the ROMs are classes that extend the ROM class. There is
some rudamentary checking to make sure that the length of the ROM
matches the declared start and end pages. (This caught what looks to
be an error in roms/apple2e, but it's hard for me to tell.)

The typing also caught an error where the character ROM was being
used for the main ROM for the apple2j version.

* Convert js/roms/cards/* to Typescript

* Convert js/formats/format_utils to Typescript

This change also seems to fix a bug with `.po` image files that
weren't being read correctly.
