[Fiona] compression engines are usually tested with different types of data to represent various use-cases.
So include for example ASCII text, binary chunks, excel files, etc. Compression of code is a typical compression workload - and
as code has lots of patterns may be quite compressible, at different ratios to standard English language text.
That said, it's not so important in DPDK to cover all data types as our focus is not on verifying the compression
engines, but just the path through the API and PMD to them. So we can replace this text if it's less confusing.

[Fiona] Simple mistake - sorry 😊

[Fiona] ok
