Feat/improve fuzz perf

[capuanob]

Pull request

This PR seeks to address the discussion concerning low coverage in fuzzing in #949. As seen here, I believe the issue was needing to append _seed_corpus to each fuzzer name in order for OSS-Fuzz to ingest it into the fuzzing runtime.

How Has This Been Tested?

I built the fuzzers on my branch and confirmed that they were properly loading their initial corpora.
