Add delay between punching and digging node

[ryvnf]

Currently there is no delay between punching an entity and starting to dig a node. If the digging time for the node behind it is instant, it is practically impossible to kill an entity and not accidentally dig the node behind it.

This adds a delay of max(0.15, m_repeat_dig_time) after punching an entity to avoid this. Because m_repeat_dig_time defaults to 0 clamping it to a minimum value is necessary. I used 0.15 because that is the hardcoded digging delay between breaking nodes with instant digging time.

How to test

1. Play Mineclonia and play on a world which has creative mode (which has instant digging with hand)
2. Give yourself a netherite sword
3. Punch the rabbit
   • On main the block behind it will be immediately broken
   • On this branch it will not be immediately broken
4. Try increasing the repeat_dig_time
   • Punch rabbit and hold dig button
   • Notice that the delay between killing the entity and digging the node behind it is increased

works

Works. 👍

(Also allows to pick up items without punching the node behind, if you want to reproduce easily.)

(Taking the same time as for dig_instantly makes sense.)
