Charts are getting stronger

Added new functionality to 📈  Charts:

• Cumulative Charts: Show cumulative values instead of daily values for date-based charts.
• Formula Properties as Y-Axis: Use Notion formula properties that return numbers as your chart's Y-axis. Great for calculated values such as totals, profits, and other computed metrics.
• X-Axis Filtering: Filter chart data based on X-axis values with powerful operators:
  - Comparison operators: =, <>, >, >=, <, <=
  - Null checks: is null, not null
  - Works with dates, numbers, and text values
• Bar Width Customization: Set custom pixel width for bars in bar charts.
