Add support for target wasm32-unknown-unknown

[av1ctor]

I was trying to build the library for --target wasm32-unknown-unknown, but no wrappers for classes and methods were being generated.

According to rust-lang/rust-bindgen#751 (comment), the -fvisibility=default flag must be passed to clang.

Also, no c++ should be linked.

Thank you for the contribution! I'll take a deeper look later. Would you be able to add a GitHub Action to test WASM? That would be incredibly helpful.

Edit: I'll also take a look at the GitHub Action later today, so no worries if you don't want to take up the task! :)

I took a look at this a second time, and I think I've just decided I'm happy with it. I'm assuming it works for your use-case, so I'd rather just merge it and move on. A Github Action for WASM testing should be it's own PR.

Thank you for the contribution!
