Enhance Time Stamper with non-blocking interactive preview, custom formatting, and alignment controls

[hiro-shikata]

Thank you for your contribution to the Time Stamper plugin. I am a heavy user of this plugin and recently improved it to meet my needs using AI-assisted coding. I believe these enhancements will be useful for everyone. I have forked the repository and updated the README with further details. I would appreciate it if you could take a look.

Description

This pull request introduces significant usability improvements and new features to the Time_Stamper plugin, transforming it into an interactive and customizable tool.

Key Changes

1. Non-blocking Interactive Preview & Drag-to-Position
   • Replaced GenericDialog with NonBlockingGenericDialog and implemented DialogListener to enable real-time updates of the timestamp preview.
   • Implemented RoiListener to automatically synchronize the text ROI's coordinates with the dialog's X Location and Y Location input fields as the user drags it on the image.
2. Custom Format & Unit Support
   • Added a customizable format field supporting placeholders such as ${dd}/${d} (Days), ${hh}/${h} (Hours), ${mm}/${m} (Minutes), and ${ss}/${s} (Seconds) to easily format elapsed time (e.g. converting 26 hours to 1d02h).
   • Added support for specifying input time units (Seconds, Minutes, Hours) for correct day/time conversion calculations.
3. Text Alignment Controls
   • Added an alignment option ("Left", "Center", "Right") to easily format text positions relative to the coordinates.
4. "Create New Window" Option
   • Added an option to draw timestamps on a duplicated image window, preserving the original raw stack.

Verification

• Built successfully using Maven (mvn clean compile).
• Verified interactively in Fiji/ImageJ:
  • Dragging the preview ROI correctly updates coordinates in the dialog.
  • Parameter changes (font size, style, color, format) update the preview ROI instantly.
  • Verified custom format behavior, text alignment, and the "Create New Window" option.
