Enhancement proposal: Use FlatBuffers to better organize + access tests input data

[ilyesgouta]

Hi,

https://flatbuffers.dev/
https://github.com/google/flatbuffers

As an optimization for the test suite, and to better organize, store and later parse and access the test vectors data (input, parameters, references, etc.), we could use the FlatBuffers library (and flatc offline tool) to better arrange the input data (in the source code, build system and on-device Flash) and split test suite code (IO, Runner, main) and data sections once downloading these to the device prior execution.

Regards,
Ilyes

@ilyesgouta I agree it would be great and more flexible. But it is a big rework of the framework.
