Force-rebuild codecs with -O3

Follow-up to https://github.com/GoogleChromeLabs/squoosh/pull/838.

I have no idea what the JS+Wasm diffs in the original PR even represented if they weren't proper rebuilds, but this time I just removed node_modules in all codecs to enforce a proper, clean rebuild for each C++ codec.

(Still think the speed-ups are worth it.)
