Add Instagram Follower option

This is available in the Instagram connector. For the total follower count, use Profile followers (id: followers_count) under the user_info table, which returns the total number of unique accounts following the profile (today’s count). If you are tracking growth instead, New followers (id: follower_count) under user_insights_day gives new followers per day (last 30 days). There are also related fields such as Profile follows (id: follows_count) and follower demographics by age, gender, and country if you need a breakdown.
