code: function some(coll, iteratee, callback) {
      return createTester(Boolean, res => res)(eachOf, coll, iteratee, callback)
  }
docs: Returns `true` if at least one element in the `coll` satisfies an async test.
  If any iteratee call returns `true`, the main `callback` is immediately
  called.

  @param {Array|Iterable|AsyncIterable|Object} coll - A collection to iterate over.
  @param {AsyncFunction} iteratee - An async truth test to apply to each item
  in the collections in parallel.
  The iteratee should complete with a boolean `result` value.
  Invoked with (item, callback).
  @param {Function} [callback] - A callback which is called as soon as any
  iteratee returns `true`, or after all the iteratee functions have finished.
  Result will be either `true` or `false` depending on the values of the async
  tests. Invoked with (err, result).
  @returns {Promise} a promise, if no callback provided
  @example
  
  async.some(['file1','file2','file3'], function(filePath, callback) {
  fs.access(filePath, function(err) {
  callback(null, !err)
  });
  }, function(err, result) {
  // if result is true then at least one of the files exists
  });
