Chunk Activity Tracker — Chunk Activity Monitor

Chunk Activity Tracker is a Minecraft library mod that collects information about player activity in individual chunks, with a particular focus on tracking time spent in them.
The mod doesn't add any gameplay features by itself but provides tools for developers of other modifications.

Features
- Tracks time (in seconds) that each player spends in a specific chunk.
- Counts the number of blocks placed by each player in every chunk.
- Additional option to save original heightmap data for each chunk.
- Efficient binary data storage format, optimized for large volumes (tested with 100 thousand chunks).
