- unpack-dfu command no longer requies a secret key to be present
- pack-dfu command raises an exception if no secret key is found

Improvements are:
- Default period is 1000ms with callback disabled.
- if period is not specified then it's not updated (previously, if period
  was not specified then it was set to -1 and running the timer callback as
  fast as possible, making the REPL unresponsive).
- Use uint64_t to compute delta_ms, and raise a ValueError if the period is
  too large.
- If callback is not specified then it's not updated.
- Specifying None for the callback will disable the timer.

This supports SDRAM having only 2 internal banks (using BA0 only), and only
11 (A0-A10) bits of address, such as IS42S16100H (512K x 16bit x 2bank).

This function includes the UART prescaler in the calculation (if it has
one, eg on H7 and WB MCUs).

stm32/rfcore: Intercept addr-resolution HCI cmd to work around BLE bug.

The STM32WB has a problem when address resolution is enabled: under certain
conditions the MCU can get into a state where it draws an additional 10mA
or so and eventually ends up with a broken BLE RX path in the silicon.  A
simple way to reproduce this is to enable address resolution (which is the
default for NimBLE) and start the device advertising.  If there is enough
BLE activity in the vicinity then the device will at some point enter the
bad state and, if left long enough, will have permanent BLE RX damage.

STMicroelectronics are aware of this issue.  The only known workaround at
this stage is to not enable address resolution, which is implemented by
this commit.

Work done in collaboration with Jim Mussared aka @jimmo.
