please do not depend on python-pip3 - security risk - use dependencies available from distribution package repositories

Instructions on Linux currently require to run `sudo python3 -m pip install -r requirements.txt`. Please consider to drop this if possible.

python pip is a security risk since it does not verify software signatures on packages it downloads. It is also a third party package manager.

Previously a bitcoin wallet was hacked that depended on a third party package manager that didn't verify software signatures.

Could you please use dependencies available from distribution package repositories such as packages.debian.org?

This is also a blocker for ever getting ZeroNet accepted into official packages.debian.org.

This is also a blocker for pre-installation of ZeroNet by default in Whonix.

https://github.com/HelloZeroNet/ZeroNet/issues/1786

Start by locating the Linux installation instructions that tell users to run `sudo python3 -m pip install -r requirements.txt`, then review `requirements.txt` and the related packaging issues #382, #241, and #1786. Done means the documented dependencies can be obtained from distribution package repositories instead of requiring pip, with the Linux instructions updated accordingly.
