Subject: [PATCH] Adding tested installation for NixOS linux (#73)

* fixing "Error: otp is not in the password store."

On nixos, following https://github.com/tadfisher/pass-otp#nixnixos and https://github.com/passff/passff/issues/419 installs a version of passff-host without any extensions. The exact suggested configuration is:

    environment.systemPackages = with pkgs; [
    ...
    (pass.withExtensions (ext: with ext; [pass-otp]))
    (firefox.override { extraNativeMessagingHosts = [ passff-host ]; })
    ...];

"..." is to be replaced by the list of all other packages installed by root on your NixOS.

This exact configuration does not add any extensions to passff-host, and passff keeps showing messages like [Error: otp is not in the password store.](https://github.com/tadfisher/pass-otp/issues/135).

This commit documents the working nixos configuration that fixes this issue.

* Update README.md

adding documentations

* suppressed spurious "dq"

* NixOS linux installation without install_host_app.sh

* expliciting the first version does not install extensions

 Note: Older Windows versions might require powershell to be installed manually as the install script uses powershell internally. Windows 10 users should be fine out of the box.
