get most stuff working again, by upgrading to newer esp-hal version

this involved adding a lot of code from the develop branch step by step
there are still some bugs, but at least i can get into the web interface
and configure stuff again \o/ … measuring and pumping is working as well

rust/src/hal/shared_flash.rs
