feat: Replace dasbus with Gio since it gets rid of depencency

[chookity-pokk]

Gets rid of dasbus in preference of the one in Gio since I couldn't get the threading to work properly in dasbus and this gets rid of a dependency 🎉.

Fixes #177

[Icy-Thought]

Built and tested on NixOS. Works as expected! Thanks for the PR!
Also, I'd like to apologize for not doing it myself, as I'd said I would.

EDIT: I lied. I just noticed that pantalaimon complains when you try to use panctl.

panctl> list-devices
Error: the following arguments are required: pan_user, user_id (see help)
