This has the advantage that the pico-serprog can stay attached to the board even while a CPU etc. runs on the board and uses the flash.

Flashprog recently added support for multiple chip selects to serprog: https://review.sourcearcade.org/plugins/gitiles/flashprog/+/ddb6d926783d4f9cbee04c7392718ed8f89daa0e This commit adds support for this feature to pico-serprog. This is useful if you want to drive multiple SPI devices on one bus with pico-serprog as it eliminates the need for reflashing the pico or changing cables.
