Bundling sqlite-vec into a go-sqlite3 build

[asg017]

Hey Nuno! Just wanted to share something I was able to make: a WASM build of SQLite, built for go-sqlite3, with sqlite-vec builtin: https://github.com/asg017/sqlite-vec/releases/download/v0.0.1-alpha.27/sqlite-vec-0.0.1-alpha.27-ncruces-go.wasm

I have a demo here of how it works, using the sqlite3.Binary trick. And the makefile, that just downloads the WASM file.

To build it it's a bit complicated, but it works. I just git clone this repo and add this patch file: https://github.com/asg017/sqlite-vec/blob/main/bindings/go/ncruces/go-sqlite3.patch

Then I build the project, all on github actions: https://github.com/asg017/sqlite-vec/blob/main/.github/workflows/release.yaml#L211-L238

And it works well! You can ignore the "database is locked" error, that's a sqlite-vec bug I'll fix:

$ make demo; ./demo
curl -L -o sqlite3.vec.wasm https://github.com/asg017/sqlite-vec/releases/download/v0.0.1-alpha.27/sqlite-vec-0.0.1-alpha.27-ncruces-go.wasm

Just wanted to share to see what you think! I don't mind the build steps, but if you have an tips would love to hear it!
