Hackathone session: bugfixes and documentation update (#869)
* ReadMe: update flashing scripts section
* Furi: add record exists method to record store.
* FuriHal: early OS init and i2c timeouts based on os ticks.
* Storage: replace malloc with furi_alloc, fix errors found by pvs.
* iButton: properly handle shutdown in cli search command
* SubGhz: proper argument type in sscanf and incorrect position of logging in switch.
