* listener such as mouse up/down, click, key & touch.
*
* @param {{billing: boolean, shipping: boolean}} opts
* If billing is true, credit card & billing address details will be requested.
* If shipping is true, a shipping name & address will be requested.
* @param {function(response:Object<string, string>)} callback [description]
* You callback is passed a single response object in this format:
* {
* // May be an empty string (no error), or:
* // unsupported - Browser doesn't support requestAutocomplete
* // disabled - Browser supports requestAutocomplete but it's disabled or can't be called at this time
* // cancel - The user aborted the process
* // invalid - Some data may be incorrect/missing
* 'err': String,
* // The retrieved data, may be missing data on err
* 'data': {
* // Card data (if billing data requested)
* 'cc': {
* 'name': String,
* 'number': String,
* 'exp-month': String,
* 'exp-year': String,
* 'csc': String
