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.
