/**
 * By default, emscripten uses memfs. The way it works is by
 * allocating new Uint8Array in javascript heap. This is not good
 * because it requires files to be copied to wasm heap each time
 * a file is read.
 *
 * HeapFS is an alternative, which resolves this problem by
 * allocating space for file directly inside wasm heap. This
 * allows us to mmap without doing any copy.
 *
 * For llama.cpp, this is great because we use MAP_SHARED
 *
