Add library with Rust bindings to target_f1 code (#68)
* Move flipper-core into a workspace

* Fix target build rules

* Add flipper-f1-sys library

* Add flipper-f1-sys dependency to flipper-core

* Remove apparently useless includes

* Build and export HAL statics

* Disable Rust dependency detection for target_f1 build

* Install libclang-10-dev in docker

* Build Rust libs every time

* remove duplicate sources from make

* clean build different example

* wip add example fn

* Implement rust_uart_write()

* fix rebuild instructions for target_f1
