feat(LED Matrix Display): Added support for a LED Matrix display

Browse Source 
This commit adds support for a specific LED Matrix display, which can be
used to show the number of found devices on a rather large display.
We (hackerspace Brixel) used this on the mini Maker Faire Gent 2019 to
show the number of found devices throughout the event
