Add Continuous integration

[AliSajid]

I have a pretty decent CI System built in my tool repo. The actual tool is pretty simple but I have a few things running that:

1. Run a few pre-commit hooks before I commit
2. Ensure that the commit messages conform to the Conventional Commit standard
3. Runs a matrix build across four rust toolchains across three operating systems (linux, windows, macos)
4. Runs the Semantic Release action to see if a new release is needed and if yes, which version marker to bump
5. Creates a new release if necessary.
6. Runs a build across the three operating systems and then uploads build artifacts to the release page.

I'd be happy to implement that in this in here.

I'm not sure I want to use semantic releases and conventional commits.
We already have a CHANGELOG, adhering to keep a changelog, which allows more freedom of expression than an automatically generated changelog.
Similarly, I feel like adhering too closely to a standard in commit messages just creates friction.
So for now, I don't want to commit to using either of these conventions.

CI would however be great for testing, but right now it would require set up for SFML, which I am going to try to transition away from before 0.2.0.

I'm gonna try to wait with CI until the port to wgpu+winit is complete, which will make both distribution and CI easier.

I think it would be wise to wait for CI. I'd be happy to help in whatever capacity.

I'm gonna reopen this as a tracking issue for eventually implementing CI.

Due to lack of time to work on this project, I'm prioritizing working on features that I want, so I'm removing this from a 0.2 milestone.
However, feel free to make a pull request for CI support.

There is Linux CI in place now. Gonna try to add Windows and Mac OS CI as well.
