include glfw as a submodule, update to 3.3.9

[MaxVerevkin]

Closes #3

[bvssvni]

Merging.

[bvssvni]

Thanks!

[MaxVerevkin]

The CI is failing but apparently that's because the CI was set up for GLFW, not the rust wrapper. Didn't catch this because of github's "first time contributor" thing :( I can send a PR with a CI which tests rust crate.

@MaxVerevkin I'm having problems on OSX. Could this be a submodule issue?

Could this be a submodule issue?

Probably no. What exactly fails?

@bvssvni Can you try running git submodule update --init --recursive?

[bvssvni]

@MaxVerevkin Works, thanks!

[bvssvni]

@MaxVerevkin Can you fix CI?

[bvssvni]

I've merged the version bump, but not published yet so you can pull before you send the PR.

[MaxVerevkin]

@MaxVerevkin Can you fix CI?

Yep, working on it.

[MaxVerevkin]

I think the readme should be update too.
