Upgrade to sdk 38.0

It would probably good to make a dev branch for this as it has not been extensively tested.

I used this awesome crate to play a bit with the flipper zero and it's really cool that this crate enables that without external bindings! Though the SDK Version was incompatible so i updated it. I also updated the documentation for some examples as I went through them

Also a small observation: I saw cargo-runner.py use run-fap from the tools. Could this be used as a runner for the flipperzero-template to avoid uploading and executing manually, improving developer experience? If so, I'd love to implement that!

Absolutely! That's a great idea!

We've considering making the tools a requirement for most development. The cargo-runner.py script was an attempt to have things work automatically; but it never quite worked 100% (especially if you wanted to support multiple OSs). So my recommendation would be to just set the runner to run-fap directly.

I updated the bindings to 38.0 since the current release candidate for 0.91 is now up to that value.

Thanks for the PR!
