PuckJS and Espruino Hub and MQTT bridge

Hmm - there should be AND... https://github.com/espruino/Espruino/blob/master/libs/bluetooth/jswrap_bluetooth.c#L1462

So unless there's a bug, jswrap_ble_filter_device should set matches to false if anything in a group doesn't match (so that's AND), and then if any group matches it returns true (so that should be OR).

// OR
filter = [{manufacturerData:{0x0590:{}}},{name:"Puck.js 4820"}];
// AND
filter = [{manufacturerData:{0x0590:{}}, name:"Puck.js 4820"}];
