When installing WS firmware, the very first GET_STATE can take several
seconds to respond (especially with the larger binaries like
BLE_stack_full).
Allows stm.rfcore_sys_hci to take an optional timeout, defaulting to
SYS_ACK_TIMEOUT_MS (which is 250ms).

The new functions provide FUS/WS status, version and SYS HCI commands:
- stm.rfcore_status()
- stm.rfcore_fw_version(fw_id)
- stm.rfcore_sys_hci(ogf, ocf, cmd)
