v0.8.6

This is a maintenance release bringing mostly bug fixes and internal improvements.

New features are of internal nature. In order to have more control over allocations, the project switched to using allocators for everything (we already had ChunkAllocator for handling allocation of memory for archetype chunks). This way, every allocation can be monitored and if necessary, allocation strategy for any given place in the project can be easily changed. Also, this gives the user the ability to override the default allocation with a custom one if needed.

The project supports allocation tracing via Tracy. This gives us the ability to see where any allocation comes from and how the situation changes over time:
