Add board WT32-SCO and WT32-SCO-Plus

Does anyone know which board I can select as a work around?

I can compile and flash but esp_highmem_get_phys_size() and esp_himem_get_free_size() both crash when called.

  esp_himem_get_phys_size();
  esp_himem_get_free_size();

Results in

E (153) spiram: SPI RAM not initialized

abort() was called at PC 0x400df714 on core 0

@zackees And ESP-IDF himem sample is here https://github.com/espressif/esp-idf/tree/release/v5.0/examples/system/himem

The internet reports that people are accessing the upper 4mb psram through high mem bank switching. At the very least calling this function should not crash the system.
