Truncate additional variables after fixed number of lines

Motivating example is data frames returned by tweetr:

I think it would be useful to have a pillar.variables_max_lines (or similar). The default would be maybe 5 lines, giving:

OTOH it's possible that this should actually be resolved in rtweet, which I'm exploring in ropensci-archive/rtweet#558.

We should also resolve this here.
