Convert DataTransfer object to a list of File objects

/**
 * A small set of the most common file extensions, bundled into the main entry so that
 * {@link fromEvent} guesses a MIME type for typeless files out of the box.
 *
 * This is the single source of truth for these defaults: the full extension-to-MIME table
 * (`COMMON_MIME_TYPES`, exposed via the `file-selector/mime` subpath) spreads this map in
 * rather than redefining these entries, so no value is duplicated across modules.
 *
 * See https://github.com/react-dropzone/file-selector/issues/127
