Test both tinygo and standard go

[egonelbre]

This adds tests for both std go and tinygo.

It also does some project cleanup:

• remove the .wasm files, because it looks like it's not necessary to commit them
• remove .work file and example submodule, because they cause more problems than they solve (in this case)
• move the examples to separate folders, because that allows different IDE-s and tooling to work with them nicely

You can pull my changes on .github/workflows/ci.yml to get the CI to go green.

@bhelx note I've rebased the code.

Thank you!

I'm generally in favor of keeping .wasm in the repo (we always find a reason to download and use these modules) -- but not a requirement.

Would like to know what @bhelx / @zshipko prefer there before going one way or the other on committing the modules.

[egonelbre]

@nilslice If they need to be downloaded one option would be to make them part of a release. (Rather than part of the source code)

[nilslice]

Yea that's preferable -- especially since Go will pull down all of this into the system cache including the wasm.

[zshipko]

Having the wasm modules in the repo is convenient, but can be pretty annoying to work with in git. Moving them to a release instead is a good idea!

[egonelbre]

Do you want me to add the release thing in this PR or in a separate one?

[bhelx]

@egonelbre this looks good to me! Let's do follow ups in other PRs
