Feat: Add WasmEdge as a UDF runtime about libsql HOT 10 CLOSED

Thanks! I even experimented a little bit with WasmEdge API back in November - https://github.com/psarna/libsql/commits/wasmedge_poc. This branch is very much not up-to-date, but once I finish some other priority items, I'll get back to it

Update: I was preempted from UDF for quite a while, but I spent some time this week to recover and rebase my early patch for WasmEdge support. I have ints and floats working as well as a functional CI (which does not pass tests yet, expected). I'm also on vacation next week, but right after that I'll try to deliver a working WasmEdge support. Then we can figure out a nice demo or use case. Thanks!

@juntao and see you at wasmio.tech! (:

Please let us know how we can be of assistance. I think the integration still needs to be done by the libsql team. But if there is any questions / feature requests for the WasmEdge SDK, we would be more than happy to help.

And after the integration, we could help developing some use cases. 🤝

That sounds great! Look forward to seeing it running!

#131 now has all the types working, but it's still not mergeable - the test suite needs to be updated in order to cover it, and we should perhaps add some automation for downloading libwasmedge if somebody decides to use it.

(I'm on archlinux where some good person already created an AUR package for wasmedge, but rest of the distros are not covered to the best of my knowledge)

WasmEdge has official packages on Fedora and Red Hat EPEL

Perfect!

I think the script can just get the slim version of WasmEdge runtime from our release page like this:

https://github.com/WasmEdge/WasmEdge/releases/download/0.11.2/WasmEdge-slim-runtime-0.11.2-manylinux2014_x86_64.tar.gz

The lib64/libwasmedge.so linked file is the one we need for Linux. Both x86_64 and aarch64 versions are available on the release asset page.

Yeah, that's precisely what I've done in the CI script that runs on Ubuntu 👌
