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). Signed-off-by: Jim Mussared <jim.mussared@gmail.com>
