skypsu: reconstructing the STP2S3010E22 Modbus register map

skypsu reconstructs the Modbus RTU register map of the SKY TOPPOWER STP2S3010E22 laboratory power supply. It provides a Python driver, read-only register scanner, local web interface and live plot. The documented map covers output control, measurements, setpoints and status flags; the author reports checking it on two units.
