- Store Emscripten cache inside node_modules/.em_cache. Docker image ships without LTO libs, so Emscripten has to rebuild stdlibs on every build otherwise. - Merge webp_enc + webp_dec build scripts. Core libwebp library is same in both cases, so there's no point in storing and building two copies of it.
