[FL-2836] Fast flash programming mode (#1782)
* updater: lowered logging level for resources unpacking; hal: implemented fast flash write mode
* hal: reworked fast flash programming; clearing most error flags on flash init; changed some flash functions return type from bool to void; scripts: fixed malformed CRC values in update bundles in certain cases;
* hal: flash: larger critical section
* hal: flash: enabling fast write inside critical section
* api_symbols: bump minor version
