fix for clock.py display date-time overlapping

[Exaga]

The date and time displayed on the SSD1306 OLED 128 x 64 pixel screen are colliding with each other - at the bottom of the date and the top of the time. In the clock.py code I added subtle spacing so that these two elements are separated. It now displays more cleanly and is not overlapping. No other changes. Everything else works perfectly.

Summary of Changes

Hello, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request addresses a display issue on an SSD1306 OLED screen where the date and time text were overlapping. The changes involve subtle adjustments to spacing and vertical positioning of the text elements to ensure a cleaner and more readable display without any collision.

Highlights

• Display Spacing Adjustment: The margin variable, used for horizontal spacing, was increased from 4 to 5 to provide more separation between displayed elements.
• Vertical Positioning Refinement: The cy variable, which determines the vertical center for drawing, was adjusted from min(device.height, 64) / 2 to min(device.height, 60) / 2 to shift the overall display area slightly.
• Date and Time Text Alignment: The vertical coordinates for drawing the date and time text were modified. The date was moved further up (from cy - 8 to cy - 10), and the time was moved slightly down (from cy to cy + 2) to prevent overlapping.

Changelog

• examples/clock.py
  • Increased the margin value from 4 to 5 to enhance horizontal spacing.
  • Adjusted the cy calculation to min(device.height, 60) / 2 for refined vertical alignment.
  • Modified the draw.text coordinates for today_date and today_time to prevent text overlap, specifically moving the date up by 2 pixels and the time down by 2 pixels relative to their previous positions.

Code Review

This pull request successfully resolves a display issue where the date and time were overlapping by adjusting margins and coordinates. The changes are effective. My feedback focuses on improving the maintainability of the code by replacing the newly introduced hardcoded numerical values ('magic numbers') with named constants. This practice will make the code more readable and easier to manage for any future modifications.

[gemini-code-assist]

While these changes fix the layout issue, they introduce 'magic numbers' (5, 60). To improve code readability and maintainability, it's a good practice to define these as named constants at a higher scope (e.g., at the top of the main function or module level). For example: MARGIN = 5, CLOCK_DIAMETER = 60. This would make the purpose of these values clearer and future adjustments easier.

[gemini-code-assist]

The vertical offsets -10 and 2 for positioning the date and time are 'magic numbers'. To make the code more understandable, consider defining them as named constants, like DATE_Y_OFFSET = -10 and TIME_Y_OFFSET = 2. This clarifies their purpose and makes future adjustments easier.
