Add TypeScript definition, bump dependencies, target Node 16

[tommy-mitchell]

Not sure if I missed anything in the definitions. Updating the dependencies doesn't seem to have any breaking changes.

...nevermind, guess something doesn't like Node 19

Here's the error:

✘ [fail]: main
✔ throws exported error error

main

test.js:9

 8:                                       
 9:   t.throws(() => {                    
 10:     parseJson('{\n\t"foo": true,\n}');

Function threw unexpected exception:

ErrorEXError {
  codeFrame: `  1 | {␊
    2 | 	"foo": true,␊
  > 3 | }␊
      | ^`,
  name: 'JSONError',
}

Expected message to match:

/Unexpected token "}"/

I generally don't test on non-LTS Node.js versions as they're generally buggy and end up with too many temporary failures.
