Use an SVG for the status icon

[RDIL]

Currently, (I don't know what triggers it), there is a bug where the icon will get super blurry. By making it an SVG, which can scale to any size required, this bug should (in theory) be fixed.

Note: this is my first time ever using xcode, so please let me know if I did something wrong.

h/t to @samuellmay for help with recreating the icon as an svg, and @alekscbarragan for help setting up the project locally

Thank you. I will attend to this when I'm next working on this codebase
