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 flash can sometimes be in an already-unlocked state, and attempting to
unlock it again will cause an immediate reset. So make _Flash.unlock()
check FLASH_CR_LOCK to get the current state.
Also fix some magic numbers for FLASH_CR_LOCK AND FLASH_CR_STRT.
The machine.reset() could be removed because it no longer crashes now that
the flash unlock is fixed.

This commit adds a script that can be run on-device to install FUS and WS
binaries from the filesystem. Instructions for use are provided in
the rfcore_firmware.py file.
The commit also removes unneeded functionality from the existing rfcore.py
debug script (and renames it rfcore_debug.py).
The device info table has a different layout when core 2 is in FUS mode.
In particular it's larger than the 32 bytes used when in WS mode and if the
correct amount of space is not allocated then the end of the table may be
overwritten with other data (eg with FUS version 0.5.3). So update the
structure to fix this.
Also update rfcore.py to disable IRQs (which are enabled by rfcore.c), to
not depend on uctypes, and to not require the asm_thumb emitter.

This allows prototyping rfcore.c improvements from Python.
This was mostly written by @dpgeorge with small modifications to work after
rfcore_init() by @jimmo.
