Consider ksni crate for Linux

[ancwrd1]

Instead of gtk and libappindicator consider using ksni which implements dbus interfaces natively (libappindicator does it via C code anyway).
The advantage is much smaller dependency tree and the requirements for build environment.

+1, I've been having issues with libappindicator3 as well on Ubuntu. After sudo apt-get install -y libappindicator3-1, it still panicks with libappindicator3 library not found! on cargo run --example linux. Simpler requirements for the build environment would be great

Please consider that not every DE/WM supports org.kde.StatusNotifierItem - see kondinskis/hyperx-cloud-flight#12

ksni is supported under a feature flag now.
