Save the corpus and use later as seed

Hi there!

A. Is it possible to save or dump the corpus that's been found so far? E.g. when I terminate the fuzzing run, it should save the corpus that's been discovered so far. Presumably the corpus path would be a command line flag.
B. When I fuzz the same target again later, using the same Domains and all that, can I reuse a previously saved corpus?

Obviously, this is not a new idea. For example, [Chromium fuzzing talks about it.](https://chromium.googlesource.com/chromium/src/+/main/testing/libfuzzer/efficient_fuzzing.md#ways-to-improve-a-fuzz-target)

A on its own is useful, even if B isn't done. I think it would be very useful to take the corpus from A, and create a unit test for every corpus element, and add that to continuous Integration and pre-commit testing.
