[FEATURE] HART protocol integration

[devaskim]

Hi team,

Would be greate to have HART connector.

From Wikipedia

The HART Communication Protocol (Highway Addressable Remote Transducer) is a hybrid analog+digital industrial automation open protocol. 

Its most notable advantage is that it can communicate over legacy 4–20 mA analog instrumentation current loops, sharing the pair of wires used by the analog-only host systems. 

HART is widely used in process and instrumentation systems ranging from small automation applications up to highly sophisticated industrial applications.
