implement fuzzing

### Search before asking

- [x] I searched in the [issues](https://github.com/fast-excel/fastexcel/issues) and found nothing similar.

### Motivation

https://github.com/google/oss-fuzz is one example of a tool that can be used to generate edge case documents that may cause issues for fastexcel when you parse the documents

Microsoft formats are very exploitable.
* Various XML based attacks (xlsx is a basically a zip of XML files) - XXE, etc.
* Zip bombs
* Legacy xls file is also very exploitable

Hopefully, fastexcel will write up a Security Model that says that lib users should be very wary of parsing excel files of unknown provenance.
