Release v4.212.3

Fixed

• Compilation now reports PLAY0801 when a projection uses one event more than once at the same level. Before, the error only appeared at executable binding, as the generic PLAY0273. A level is the root, one children or nested block, or one variant. Within a level, from, remove with, remove via join and clear with share one set of events, and join events have their own. Chronicle allows one use of an event type per projection level. (#675)
• The task-tracking counter example in the projections documentation no longer uses the same event in two from blocks. (#675)
