Adding support for sniffing and reactive jamming of advertisements.

[RCayre]

Adding advertisements-related features, such as sniffing or reactive jamming.

Multiple options have been added to the UI in order to communicate with the firmware version supporting advertisements sniffing and reactive jamming (btlejack-firmware PR #10). It allows to configure a filtering policy in order to accept or drop specific frames, and provide a pattern to reactively jam some specific frames.

It includes a simple advertisements dissector (dissect/advertisements.py).
The usage is described in the code itself.

What is the status of this PR? It looks that sniffing and jamming advs is not supported by btlejack v2.0

[RCayre]

As far as I know, virtualabs has made signifiant modifications in the code of btlejack in order to support BLE 5.0 sniffing, ans doesn't plan to include advertisements sniffing. This PR should be consequently adapted anyway. However, the forked version is still available and support 4.x advertisements sniffing/reactive jamming. I guess it may be closed.

Hey @RCayre ,
Did you modify the firmware for your patch ? if yes did you publish somewhere the sources ?

[RCayre]

Yes, the forked firmware is available here:
https://github.com/RCayre/btlejack-firmware

It is compatible with Mirage (module ble_sniff or ble_jam, interface microbit, examples are available in the documentation) and this modified version of btlejack:
https://github.com/RCayre/btlejack

edit: please note that it doesn't support advertising features introduced in the 5.0 spec (extended advertising, periodic advertising) (nRF51 is not able to use LE 2M and LE Coded PHYs anyway).
