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.

Major update for BMS C1 v0.3
This commit contains major updates of the PCB after the first prototype
build-up and testing. Changes include:
- Single PCB instead of stacked PCBs to simplify design and reduce cost.
- STM32 MCU was removed due to supply shortage. Only ESP32-C3 supported.
- Custom connectors replaced with off-the-shelf Würth Power Elements.
- 5V power rail removed to simplify design (CAN runs on 3V3 transceiver).
- Larger Shunt with improved footprint.
- Optimized layout to reduce distance between IC and shunt.
