6.1.6: Vendoring unneeded precompiled files

[dvzrv]

Hi! I package this project for Arch Linux. Upon installation I noticed, that precompiled libusb libraries are installed to site-packages, which I have to remove manually.
Please rely upon https://pypi.org/project/libusb/ (which can be built from source) instead of vendoring precompiled files, as they can not be verified and are on top also installed for architectures that do not require them.

Hi! We do not have capacity to maintain and release new versions of this utility.
A new utility with the same name and feature set is made. It can be found here: https://www.nordicsemi.com/Products/Development-tools/nrf-util
