Convert Blob sources into Files.

The BlobLoader extension can be configured with the BlobLoaderOptions object. 

import { defineFilePond } from 'filepond';
import { locale } from 'filepond/locales/en-gb.js';
import { BlobLoader } from 'filepond/extensions/blob-loader.js';

defineFilePond({
    locale,
    extensions: [
        // Add the BlobLoader extension and configure with BlobLoaderOptions object
        [BlobLoader, {
            // add any mime types that can't be derived automatically by FilePond
            mimeTypeMap: { 'application/ld+json': 'jsonld' }
        }]
    ]
})
