nix: rewrite nix flake from ground up and introduce home-manager module (#44)

* rewrite nix flake and move default package

* revert: remove .envrc

* feat: create home-manager module

big W

* fix: properly parse null for config.plugins

* build plugins from template derivation

* build plugins from template derivation

* cache each plugin individually

* pass name and derivation to template derivation

* fix: rework the devShell

* fix: add missing flake-parts input

* feat: make anyrun not build plugins

it only builds plugins on the anyrun-with-all-plugins package

* chore: write documentation about HM module

* fix: specify pname for plugins

* nix: flake-parts follows nixpkgs

* nix: formatting via alejandra

+The flake provides multiple packages:
+ - anyrun (default) - just the anyrun binary
+ - anyrun-with-all-plugins - anyrun and all builtin plugins
+ - applications - the applications plugin
+ - dictionary - the dictionary plugin
+ - kidex - the kidex plugin
+ - randr - the randr plugin
+ - rink - the rink plugin
+ - shell - the shell plugin
+ - stdin - the stdin plugin
+ - symbols - the symbols plugin
+ - translate - the translate plugin

+#### home-manager module
+We have a home-manager module available at `homeManagerModules.default`. You use it like this:

+      plugins = [
+        # An array of all the plugins you want, which either can be paths to the .so files, or their packages
