Can't run module with tail calls

[womeier]

As the title suggests, I'd like to run a Wasm module with tail calls.
Other proposals can be configured in the Config class, but not tail calls.

Would greatly appreciate it if there was an option for that as well.

Thanks for the report! Wasmtime supports the underlying feature here but the config option hasn't been surfaced yet from the Wasmtime C API into these bindings. If you're up for it a PR to add a method to expose this would be greatly appreciated! It'd look quite similar to the other methods of exposing wasm features.

thanks!

Created a PR, but need help with testing it, see the PR.
