✨ feat(input): Migrate to moq for input transmission (#38)

## Description

**What issue are you solving (or what feature are you adding) and how
are you doing it?**

We cannot use golang for our input binary as we will be redoing the
Webtransport stack, plus we will have to use CGO in-order to hook into
X11. Like what [neko](https://github.com/m1k1o/neko) does.

However, we could go down the Rust route, where X11 mouse/keyboard
drivers are in pretty, and moq-rs (the MoQ library using Webtransport)
works really well. So, that is what am trying to do here; implement
input using rust.
