Local options (localOptions or lo)

import { Denops } from "../mod.ts";
import { localOptions } from "../variable/mod.ts";

export async function main(denops: Denops): Promise<void> {
  // Set option
  await localOptions.set(denops, "filetype", "world");

  // Get option
  console.log(await localOptions.get(denops, "filetype"));

  // Reset option
  await localOptions.remove(denops, "filetype");
}

Note that localOptions.get() returns defaultValue when the option is falsy.
