Hiroyasu Nishiyama 218794be77 Initial support of merge & reduce mode for JOIN node (#1546)
* initial support of merge mode of JOIN node

* initial support of reduce mode of JOIN node

* update info document of JOIN node

* add tests for merge & reduce mode of JOIN node

* tidy tabs & spaces

* add test for too many pending messages & related fixes

* add an test for reduce mode of JOIN node

* change order of modes of SWITCH node

* add initial topics entry of merge mode

* fixed descriptions on "reduce right" checkbox

* fixed update of typedInput field of reduce mode

* fixed a typo in info document of JOIN node

* allow empty string in JSONata input field of reduce mode

* fixed a typo

* fixed error in reduce mode description
