Setup dev container

[calebchalmers]

We should create a container which includes all the tools needed for building this repo. It should also interface nicely with the dev container standard (mostly for the VS code extension).

Ideally this will be able to flash to the robots via USB passthrough. This will make it much more useful for development, as well as for deployment to the CV board to enable remote dev board flashing.

Using the default ARUW Dockerfile included with the template projects almost works, but I had some issues:

• The GCC version is older, causing compilation errors, and should rather be 10.3.
• There were permission issues where all the code was root (this could be a VS code quirk with the dev containers)

I had trouble cloning directly from GitHub, so I cloned the repo manually and then opened it with the included dev container.

I think the best thing would be to make our own Dockerfile and build images directly from that.
