Stm8s Discovery & MODBUS RTU

I've tried to look for a Modbus RTU version for the STM8s.
It seemed that nothing exists yet.
So I decided to write a tiny version of it for the only purpose of the most basic RTU functions that do the job, which are
function code 03 = READ HOLDING REGISTER
function code 16 = PRESET MULTIPLE REGISTER
I already tested a preliminary version of the code with several MB RTU masters (taken from the web).
As soon I'll will make the code available if someone is interested.

Good job
Stefano
