Fix 2mg header parsing and add tests (#127)
Before, the offset for `FLAGS` in `2mg.ts` was `0x0A`, which is
incorrect according to the spec at:

https://apple2.org.za/gswv/a2zine/Docs/DiskImage_2MG_Info.txt

Now, all of the fields in the 2mg header are described, including
their lengths and any constraints.  These constraints are enforced by
`read2MGHeader` and tested by new tests.

Add the recommended eslint plugins for TypeScript (#121)
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.

Keep track of disk sides (#87)
Disk side information was being dropped and thus not displayable in the UI. This plumbs the value through various formats and adds some light testing.

Also fixes an issue where URL encoded hashes were not properly interpreted.

DOS 13-sector tests and fixes (#53)
Like the DOS 3.3 and ProDOS sector order issues, this change fixes the
physical order of the sectors on 13-sector disks when nibblized.

This change also adds tests for the 13-sector format to verify the
sector order.

One of the crazy things is that _Beneath Apple DOS_ failed me in this
instance because it doesn't discuss what happens to the last byte in
"5 and 3" encoding anywhere (AFAICT). I went back to the DOS 3.1
source released by the Computer History Museum here:

    https://computerhistory.org/blog/apple-ii-dos-source-code/

The code is in `appdos31.lst` in the `POSTNIB` routine on line 4777.

ProDOS image format tests and fixes (#51)
Like the DOS 3.3 sector order issues in #49, this change fixes the
order of the physical sectors on the ProDOS disk when nibblized.

This change also adds tests similar to the DOS 3.3 tests to verify the
sector order.

Because the DOS 3.3 and ProDOS tests are so similar, the utility
methods have been refactored into their own file.

DOS 3.3 image format tests and fixes (#49)
* Adds an initial test for DOS format (.do) files

* Fix physical sector order when nibblizing DOS 3.3 ordered images

Before, when `.dsk` or `.do` images were nibblized, the resulting
track had the sectors in the wrong physical layout.

Now the nibblized track has the correct physical layout (all sectors
in order) which results in the correct DOS 3.3 layout as well.

There is also a test that verifies the order.

* Add another test for a non-zero sector

The new test checks that the values in physical sector 1 are those for
DOS sector 7.

* Add test for all physical sectors on all tracks

This change also removes a few stray console.log calls in the test.
