Optimize wasm file

[etrombly]

Stripping the debug symbols and optimizing with wasm-opt cuts lg2.wasm down from 6.3Mb to 1.1Mb, and seems to execute a little faster (only minimally tested). May want to see if you can do the same thing for the packaged version.

wasm-opt --strip-debug -O3 emscriptenbuild/libgit2/examples/lg2.wasm -o emscriptenbuild/libgit2/examples/lg2-stripped.wasm

If you look at the latest released version of wasm-git then lg2.wasm is 803KB: https://www.jsdelivr.com/package/npm/wasm-git?tab=files

That was based on using build.sh to build a local copy (I had also pulled in v1.7.2 of libgit2). Are you doing additional steps for packaging after that? May just want to mention in the build instructions how to optimize the wasm output.

If you run build.sh Release you should get the optimized version. You can also see how the release pipeline does this here: https://github.com/petersalomonsen/wasm-git/blob/master/.github/workflows/publish.yml#L28
