DMX Presets with MongoDB2 and DMXUSBPRO node

This is a flow to show how the node-red-contrib-dmxusbpro node can be used. It uses dashboard sliders to set DMX values, stores presets in a mongodb collection, and recalls the presets which can control DMX hardware using the Enntec dmx usb pro. You will need to set the serialport port-name in node-red-contrib-dmxusbpro node. You also set the DMX starting address in the node-red-contrib-dmxusbpro node. Adapted and simplified from node-dmx package https://www.npmjs.com/package/dmx requires node-serialport module.
