[Feature] Add a preview rows feature to GIS File Input

[scali]

What would you like to be added:

The transform GIS File Input doesn't support the data previsualization.

The feature would be very similar of what is actually possible for transforms like CSV file input or Text file input with the Preview rows feature.

Alternatives:

It is possible to view the data by runnning the pipeline.

Has the feature been requested before?

No

If the feature request is approved, would you be willing to submit a PR?

Yes, but no time to work on it soon
