W25 Flash driver

This is a generic async driver for the W25 flash chips from Winbond.

Supported series:

• Q
• X

More series support is welcomed!

Defmt is also supported through the defmt feature.

This crate is adopted from https://github.com/tweedegolf/w25q32jv

TODO

• Fast read support. So far there's only support for the normal read, so don't use a SPI speed of > 50Mhz
