feat: disable URL state sync option when running in datasette-lite

[hydrosquall]

Motivation

• Make plugin usable without needing to use server-side datasette ( Get JavaScript working (table.js, plugins and more) simonw/datasette-lite#8 )

Background

• feat: proof of concept initialization hook for instantiating JS plugins in datasette-lite #26 is mostly working, with caveats
  • Reusing the URL hash currently confuses the datasette lite router. In regular datasette, this route is not sent to the server. In datasette lite, this information is used to simulate the server
  • Until we figure out a way to separate URL search params / URL hash, or add a pure JS API for doing browser routing in datasette-lite, it's best to disable the "save URL state" feature entirely when running in datasette-lite mode.

Implementation Notes

• We could make controlling this part of Datasette plugin config in the long term
• In the short term, in the interest of having a good default experience "out of the box", I think I'll use awareness of running in the datasette lite environment to pass a param into onLoad.

Lines 49 to 51 in 371b9f8

	if ((window as any).__IS_DATASETTE_LITE__) {
	document.addEventListener("DatasetteLiteScriptsLoaded", onLoad);
	}

When this setting is disabled, we can ignore the Jotai hook.

const [explorerMetadata, setExplorerMetadata ] = useAtom(explorerMetadataAtom);

Fixed for most workflows in #30 .

Can reopen if/when nteract/data-explorer#83 is completed to also handle the case where interacting with the "table" component's filters could modify URL params too.
