Easily building self-contained Python executables with uv

I was getting frustrated trying to figure out how to get a wheel and pex built in my work's uv monorepo/workspace. I've been used to how easy it is to build a go binary for any platform. Anyway, once I figured it out, I figured I should publish my cleaned up findings. This is great for deploying self-contained python executables and not needing to worry about any packaging non-sense at runtime.
