* FuriHal: furi_hal_serial, add custom IRQ func
* Fix PR review issues
* Implement basic external module detection and echo
* Update api symbols for f18
* Minimally working implementation (can create directory via rpc)
* Make expansion protocol parser a header-only library
* Rename a function
* Improve thread syncronisation
* Implement multi-packet transmissions
* Improve test application
* Clean up expansion worker code
* Send heartbeat when host is ready
* Update API symbols
* Add draft documentation
* Expansion worker: proper timeout and error handling
* Expansion worker: correct TX, do not disable expansion callback
* Expansion protocol: pc side test script
* PC side expansion test: trying to change baudrate
* Working comms between 2 flippers
* Cleaner exit from expansion worker thread
* Better checks
* Add debug logs
* Remove unneeded delays
* Use USART as default expansion port
* Refactor furi_hal_serial_control, fix crash
* Improve furi_hal abstraction, wait for stable rx pin
