Newaetech/chipshouter-picoemp: Why not run micropython on your EMFI tool?

Background The ChipSHOUTER is a high-end Electromagnetic Fault Injection tool designed by Colin at NewAE Technology. While not the first commercially available EMFI tool, ChipSHOUTER was the first "Easily purchasable" tool with extensive open documentation. This PicoEMP project is not the ChipSHOUTER. Instead it's designed to present a "Bare bones" tool that has a design optimization focused in rough order of safe operation, cost, usability, performance. The full ChipSHOUTER detects the missing connector tip and refuses to power up the high voltage, the PicoEMP does not have this failsafe! This was fine provided you use the tool correctly, but of course there is always a risk of grabbing the electrically "Hot" tool! This common design choice happens because the easiest way to design an EMFI tool is with "Low-side switching". PicoEMP gets around this problem by floating the high-voltage side, meaning there is no electrical path between the EMFI probe output and the input voltage ground. ChipSHOUTER has a controlled high-voltage setting from 150V to 500V. PicoEMP generates ~250V, there is some feedback but it's uncalibrated.
