Tray with openHASP remote

This is an extension to the cup holder tray project to add a openHASP remote that uses a Seeed SenseCAP D1 [1]
as display. The idea here is to use openHASP to send MQTT events to homeassistant which in turn will send
IR commands to a Broadlink RM4PRO [2] to control TV, receiver and HDMI switches. This makes it very convenient
to switch between consoles while still sitting.
