[Suggestion] Add stats for recurring expenses #508
Description
With recurring expenses (#5) being mostly implemented, it would be logical to have some new entries in the "Stats" tab for the cumulative of recurring expenses in each recurrence period (daily, weekly, monthly, yearly).
Although definitely not the primary goal, this would allow Spliit to be used as a basic subscriptions manager. I would love to have both the ability split and track subscriptions within a single app, and I found no quality options with existing apps in Google Play.
