Stats Page pagination / useAttempts pagination

[solderq35]

Issue

• The stats bar chart (especially on Drill > specific drill type > stats) will crash certain Android devices due to a lack of memory
• Possibly related, concerning bar chart render performance: BarChart updating too slowly #108

Possible solutions

• Locally limit the number of bars being stored in frontend state, to reduce amount of bars rendered
• [Maybe] Paginate Firestore requests (useAttempts hook)
  • Documentation: https://firebase.google.com/docs/firestore/query-data/query-cursors
  • Might be trickier to implement than locally limiting bars
• Add "next" and "previous" buttons on the left / right sides of graph so user can go to "next page" or "previous page" of bar chart on the stats page
