Support QSPI and OSPI flash chips larger than 16 MB #56

Esptool already supports writing to flash chips larger than 16 MB. Octal and quad flashes had to been implemented differently. This is probably relevant for ESP32-S3 only for now. I assume it will be a desired feature for ESP32-P4 as well.

I just had a discussion with Scott and we concluded that possibly this could be implemented without esp-hal which could make things much easier. Just to do ROM calls with flash driver implementation. We need to make easy for the community to contribute new flash drivers.
