* Add sqlite3_wasm_vfs_create_file() to replace Emscripten's ↵stephan2022-11-02
| | | | | FS.createDataFile() in a (mostly) VFS-agnostic way. Add a test for worker1's export (to bytearray) support. Re-add worker1 open-from-bytearray using sqlite3_wasm_vfs_create_file() but it's untested (requires a new interactive test app or maybe reconsideration).
