Define the test format

Just like the web platform tests here:
https://github.com/web-platform-tests/wpt/blob/master/html/syntax/parsing/resources/adoption01.dat

We should provide a set of tests glob libraries can test against to determine if they support the standard.

To do that, we need to decide what format these tests should be.

Right now, there's some examples as JSON in the repo:
https://github.com/43081j/standardglob/tree/main/tests

But these don't account for configurable features (e.g. `dot: true`) yet.

Also very importantly: these need to be consumable by any language, not only JS projects.
