Support for daisy chained MAX7219 seven segment displays

[hpagonis]

Hello developers,

I have three MAX7219 eight digit seven segment displays and I managed to daisy chain them together by altering the xdsp_15_tm1637.ino driver and the DisplayWidth command. I would like to contribute to the Tasmota project if you agree.

Documentation:

• MAX7219 data sheet

Hey @hpagonis any update on this?
Looks like the code is in these commits, https://github.com/hpagonis/Tasmota/commits/max7219-daisy-chain/
@arendst could it be rebased and merged? It would be a great feature to add 😄
