HMIStressTest INO start

Added HMI draft and prepared code for stress testing

Added PDF schematic for reference

Added first draft of Op-amp based circuitry Also some rationalisation of the components to avoid near-duplicates (e.g. 0.1uF 50V caps)

Merge pull request #15 from martinroger/Martin-dev New R sensing circuit, PCB update

Continued merge of both branches Cleaned up PCB, extended 10mm to the right and pushed the power conversion stages to the right of the board. Left Resistive sensors out in the open as they will be changed, increased available real estate for resistive sensor

Consolidated merges

Merge branch 'main' into Martin-dev

Merge pull request #19 from martinroger/Alex-dev Power input and 5V regulator updates

Update VXDash.kicad_pcb Implemented current schematic changes Capacitors near PS1 Capacitors for Water T sense Water T sense relocated to the CMOS
