Describe the bug

• Node.js version: 14.16.0
• OS & version: -

Actual behavior

It seems that since https://github.com/sindresorhus/quick-lru/releases/tag/v6.0.0 quick-lru is not compatible anymore with keyv:

    Type 'QuickLRU<unknown, unknown>' is not assignable to type 'string | false | StorageAdapter | undefined'.
      Type 'QuickLRU<unknown, unknown>' is not assignable to type 'StorageAdapter'.
        Types of property 'set' are incompatible.
          Type '(key: unknown, value: unknown, options?: { maxAge?: number | undefined; } | undefined) => QuickLRU<unknown, unknown>' is not assignable to type '(key: string, value: any, ttl?: number | undefined) => any'.
            Types of parameters 'options' and 'ttl' are incompatible.
              Type 'number | undefined' is not assignable to type '{ maxAge?: number | undefined; } | undefined'.
                Type 'number' is not assignable to type '{ maxAge?: number | undefined; } | undefined'.

Expected behavior

Either
1- Change signature of quicklru .set so that the metod is compliant with keyv StorageAdapter interface
2- Remove suggestion of quick-lru usage inside the readme
