Closes #15

Preview:

I redid the file imports to map a filename to its FeatureCollection so we always have a reference to the file path, which is then passed onto the App. Here, files are filtered into a valid and invalid group using a rigorous and terrible method (very open to suggestions). All valid geo json are passed in as usual. If any invalid files are found, a modal is opened that lists their corresponding file paths. To close the modal, users can click the "x" icon or click outside of the modal.

Tested on an empty directory, a directory containing a half-empty json and a working geo json, and a directory containing working geo json files.

In general, this looks great. I'm a fan of listing the files that weren't able to load, and loading the ones that can 👍

We could consider using a JSON Schema validator. There are pre-written schemas for GeoJSON out there, and lots of libraries that can validate JSON files (plus they can provide detailed parsing error messages!)

We should add a header and description value to FileErrorModalProps to make it easier to reuse in the future.

Likewise for the error content, the list could be specified via a prop.

Just for naming, could we move this file to FeatureCollection.schema.json?
