Optimize binary testing data

[KedoKudo]

Is your feature request related to a problem? Please describe.

The testing data in the repo (tpx3 files) are relatively large and causing issue when pulling from a network with limited bandwidth.

Describe the solution you'd like

Replace the large testing data file with smaller and more portable test data with the following features:

• the file size should be below 100MB (prefer smaller than 10MB)
• the file should contain both time packet (tdc, gdc) as well as data packet (hits)
• the file should contain rollover events
• the file should contain actual clusters instead of static noise from electronic backgrounds

Describe alternatives you've considered

The alternative would be using git lfs for large data in the future

Additional context

Make sure the remove the large file from all branch and git history so that they are not hidden in the history block.
