Just published a plugin called the ICS Parser. This plugin will let you parse an iCalendar file (.ics) url to view in a repeating group and save to your database.
NOTE: There are subtle variants of ICS files and so if your ics file link is not returning a date in the plugin, reach out to me via DM with a link to your file and I will update the plugin to accommodate your ics file variant.
