Suggestion: Create util for downloading CSV (and maybe similar stuff)

[MB-web]

We have this in some projects:

`export type Row = (string | number)[];
export type Payload = Row[];

/**

• Handles downloading an array as CSV list.
  */
  export default function downloadCsv(payload: Payload, fileName: string, delimiter = ','): void {
  const content = \ufeff${payload.map(row => row.join(delimiter)).join('\n')};
  const anchorElement = document.createElement('a');
  const mimeType = 'text/csv;encoding:utf-8';

anchorElement.href = URL.createObjectURL(new Blob([content], {
type: mimeType,
}));
anchorElement.setAttribute('download', fileName);
document.body.appendChild(anchorElement);
anchorElement.click();
document.body.removeChild(anchorElement);
}
`
