v1.2r1

Seems to be working with Godot 4.x (tested with 4.0 and 4.1 branches, though not exhaustively).

Only downside is a bug has appeared when running int Godot 4, where bulletspawners' cached volleys lose their data after their first use, not sure why. For now I've just disabled the caching behaviour, as it's not strictly necessary for good performance.

This release will be replaced when I have automated builds working.
