If you want to make EdgeDB's base64 encode function faster & use less memory

[Jarred-Sumner]

Change this code: https://github.com/edgedb/edgedb-js/blob/b2d9ef57a9efddcc3737ecd9709533650f09ac36/packages/driver/src/primitives/buffer.ts#L35-L44

To something more like:

if (typeof Buffer === "function") {
  decodeB64 = (b64: string): Uint8Array => {
    // @ts-ignore
    return Buffer.from(b64, "base64");
  };
  encodeB64 = (data: Uint8Array): string => {
    // @ts-ignore
    //  - Avoid cloning the contents of Buffer
    //  - Avoid creating a new Buffer if it is already a Buffer instance
    const buffer = !Buffer.isBuffer(data) ? Buffer.from(data.buffer, data.byteOffset, data.byteLength) : data;
    return buffer.toString("base64");
  };
}

Thanks for the tip @Jarred-Sumner! I'll take a look. Love these easy wins.
