[FEATURE] last.fm search result caching

[Delivator]

Is the feature request related to a problem. Please describe it.

Last.fm playlist downloads run into errors a lot on my machine and when it does, it crashes fatally and I have to rerun the command. And by far the slowest part is the search for tracks on the services.

Describe the solution you would like.

A solution would be to cache/write to a simple txt file all results streamrip found in the first step so when running the command again, it skips the search step.

Describe alternatives you've considered.
