function unwatchFile
Usage in Deno
```typescript import { unwatchFile } from "node:node__fs.d.ts"; ```
unwatchFile(filename: PathLike,listener?: StatsListener,): void
Stop watching for changes on `filename`. If `listener` is specified, only that
particular listener is removed. Otherwise, _all_ listeners are removed,
effectively stopping watching of `filename`.
Calling `fs.unwatchFile()` with a filename that is not being watched is a
no-op, not an error.
Using [watch](../.././node__fs.d.ts/~/watch) is more efficient than `fs.watchFile()` and `fs.unwatchFile()`. `fs.watch()` should be used instead of `fs.watchFile()` and `fs.unwatchFile()` when possible.
