Continuous fuzzing by way of OSS-Fuzz

[DavidKorczynski]

Hi,

I was wondering if you would like to integrate continuous fuzzing by way of OSS-Fuzz? Fuzzing is a way to automate test-case generation and can be used to find unexpected exceptions in Python. In this PR google/oss-fuzz#8189 I did an initial integration into OSS-Fuzz, and this initial fuzzer should be enough to cover the logic of digest.

If you would like to integrate, the only thing I need is a list of email(s) that will get access to the data produced by OSS-Fuzz, such as bug reports, coverage reports and more stats. Notice the emails affiliated with the project will be public in the OSS-Fuzz repo, as they will be part of a configuration file.
