add `serialize` and `deserialize` functions to `diesel-wasm-sqlite` backend

[insipx]

Serialize docs: https://sqlite.org/c3ref/serialize.html Deserialize docs: https://sqlite.org/c3ref/deserialize.html SQLite WASM: https://www.sqlite.org/wasm sqlite3 WebAssembly C-Style API documentation: https://www.sqlite.org/wasm/doc/trunk/api-c-style.md wasm-bindgen (rust -> js ffi) docs: https://rustwasm.github.io/wasm-bindgen/reference/attributes/on-js-imports/index.html

the serialize and deserialize methods on RawConnection are commented out: https://github.com/xmtp/libxmtp/blob/bb18b61df2e310b7c23ad222cb2c167fa9b28ae9/diesel-wasm-sqlite/src/connection/raw.rs#L89

They still use the raw C-bindings from libsqlite3-sys rust crate. We want to convert these to use the WASM bindings.

• Add the required methods to ffi.rs and package.json for serialize/deserialize
• add the methods to raw.rs
