create a method which recieves aid and returns issuerName

@HunnySajid , we do not have a method in signify-ts to retrieve an aid by its aid string. What we can do is in the listIdentifiers function in the browser, it to iterate until we gel all aids, something like

  const listIdentifiers = async () => {
    validateClient();
    let aids: any[] = []
    let start = 0;
    let total = 25;
    while (start < total) {
      const res = await _client?.identifiers().list(start, start + 24);
      aids = aids.concat(res.aids);
      total = res.total;
      start = res.end + 1; 
    }
    return aids;
  };
