Apply considerable acrobatics to get the JS/WASM deliverables building to and loadable from a directory other than the one which contains the app-level code. Requires an only-slightly-leaky abstraction of passing a URL argument when loading sqlite3.js but provides much greater flexibility in where the JS/WASM files are located.
