Small Fixes
- Removed Prius MG1 detection, wasn't reliable
- Added support for CAN scaling < 1. But now you cannot scale up more than 32!
- FOC: running offset calibration continuously while idle -> smoother low speed operation
- Custom charge PWM handling for Prius hardware (alpha, needs testing)
- Bugfix in temp calc module when reaching lower limit of lookup table use minimum
- Force precharge off in bootloader, also fixes Tesla misdetection
