Add initial fuzz corpus files (#73)
Browse files Browse the repository at this point in the history 
### What
Add a new fuzz corpus with multiple seed files.

### Why
Adding fuzz testing, which I've been playing around with. The corpus is made up of test vectors from SEP-23. I added a test that was missing as well.
