Helper to access a specific frame of test data at a fixed memory location.

The series of test frames is generated on demand, but remains in memory thereafter, similar to real data accessible from some kind of source stream. Each of these generated test frames filled with different yet reproducible pseudo random data. Client code is free to access and corrupt this data.
