"""Полное восстановление SPI рации из заводского эталона (radio-spi-dump.bin, до экспериментов).

Пишет все регионы codeplug/калибровки CPS-протоколом (USART6) из WSL через powershell.exe.
Рация — в ОБЫЧНОМ режиме. Возвращает рацию к состоянию на момент дампа.

Регионы (region_id, address, size) — из rt4d-cps constants.
