Refs #50
This implements our first fuzzer. It replicates the process that the
bulik_compare_swapcreated, but in such a way that the fuzzer provides the batches. After a couple of hours across 8 cores, the fuzzer found a new bug. After fixing that bug (will be pushed in next commit to main), the fuzzer then ran for another 6 hours with no additional crashes. I'll be continuing to run it for the next day or two.I'm not closing #50 because another fuzzer should be written that executes a wide variety of operations in a sequential manner. This test focuses on batching because that's where I discovered a bug this weekend. It would be nice to have some fuzzing validation against the remaining operations -- and it can be less restrictive due to not needing to be batched.
This commit also temporarily changes a few debug_asserts into asserts. This will be addressed in a follow up commit.
