v3.2.2: Switch to SMD terminals instead of press-fit Rationale: These are easier to manufacture (no additional step required) and the PCB can be mounted onto a heat sink without any milling required.

Remove FUSE_DETECT circuit Q13 was not properly tied to ground, so it was not switching on the voltage divider. A voltage divider that is continuously on would draw current even in deepsleep mode, so it is not viable for a BMS. I could not come up with an easy circuit that allows monitoring the voltage without any power consumption, so the fuse diagnosis mechanism is removed for now.
