Adjust the number of features printed by print.sfnetwork

[agila5]

Is your feature request related to a problem? Please describe. I'm always frustrated when the printing of an sfnetwork object stops after a few rows (and the problematic rows remain hidden).

Describe the solution you'd like I would like to implement an option or an extra parameter to decide how many features should be printed for the active and inactive geometries. I think that, at the moment, we hardcoded the values 6 and 3, respectively. I'm not saying we should modify the default values, just make them modifiable.

Describe alternatives you've considered Not sure 😅

Makes sense to me! This should not be too hard right @loreabad6 ?

Not sure how to document the new params since there is no Rd file for print.sfnetwork. Moreover, feel free to change the name of the new parameters.

This is fixed now thanks to @agila5

[agila5]

Hi! Quick question: what do you think about including a new example in ?sfnetwork to present these new parameters? I keep forgetting their names and, AFAIK, they are not documented anywhere but in the news file and in the code. If you agree, I can add a PR.

Agree :+1:
