React Fragment Prerender

Server render React components into strings and populate with data from any source. Server string will be put into a fragment file with separate hydration script bundled with esbuild. Client only has to include the hydration script for the fragment (client/out/fragment/**) as well as the html (example include with vite-handlebars-plugin) which already includes the root element of the component for the hydration call (hydrateRoot).
