feat: support a way to override fetching behavior

What's the best way to cache responses with ohmyfetch via an LRU cache?

With axios, I've used axios-extensions's "cacheAdapterEnhancer" like so:

import { cacheAdapterEnhancer } from 'axios-extensions';
import LRU from 'lru-cache';
const ONE_HOUR = 1000 * 60 * 60;
const defaultCache = new LRU({ maxAge: ONE_HOUR });
const defaults = $axios.defaults;
defaults.adapter = cacheAdapterEnhancer(defaults.adapter, {
  enabledByDefault: false,
  cacheFlag: 'useCache',
  defaultCache,
});

which caches responses when I explicitly add useCache: true to the request.

Is there a similar enhancer for ohmyfetch, or one planned, or an example of how to implement caching with ohmyfetch?

The issue names no specific file or test. Start by locating ofetch's request entry point and existing request-option documentation, then determine whether the intended result is a supported caching override or an implementation example; done should be a documented, testable resolution to that choice.
