Unofficial Factorio 2.1 fix of Tree Cleaner. Original mod by GPS; 2.1 fix by kfsone.

Tree Cleaner marks dead trees for deconstruction around every connected player, so construction robots clear them away.
It can also flag cliffs for deconstruction (setting, on by default).

This mod replaces the original TreeCleaner. It is flagged incompatible with it: disable or remove the original before using this one.
Prototype and setting names are unchanged, so existing saves and your saved settings (runtime-global: range in chunks, and cliffs on/off) carry over.
The mod keeps no script state, so nothing needs rebuilding when you swap it into an existing save.

Settings (map settings, runtime-global):
- Range around each player (in chunks), 0 to 10, default 3 (0 effectively disables the mod).
- Flag cliffs for deconstruction, default on.

Changes versus the original: Factorio 2.1 compatibility (info.json) and the rename. The Lua code is unchanged.
