Retry request after API error

[bmesuere]

See https://github.ugent.be/unipept/unipept-cli/issues/13#issuecomment-16365 for the question

We could use queue_front to implement this. As @bmesuere said, hydra.run is a blocking call but in the response handlers, new items can still get queued.

Some comments from @tvwillem in unipept/unipept#333:

I'll briefly explain what I do now:
if the request times out -> a message is printed to stderr. We continue with the rest of the input.
if the request produces an error -> the error is saved in ~/.unipept (with accompanying message to stderr). We continue with the rest of the input.

What I think should be done:
Log the entire input for with requests failed in a convenient file so it can be easily resumed.
