add build-essential to dependencies install step in readme (#106)

* add build-essential installation to readme steps, rustup makes an assumption thats the C linker is already installed. on the fresh ubuntu 22.04 system i am installing on build-essential wasn't installed leading to an cc linker not found error on rust compilation.

* readd in 'debian-based systems' (forgot to save before previous commit)
