Improve logger performance

[jwaa]

Is your feature request related to a problem? Please describe.
Currently we have Logger to log data in our worlds. However, these are quite inefficient. It slows down the world when we add more and more loggers to the world. This occurs in the Coactive Teaming research project.

Describe the solution you would like
A way that improves on the efficiency of continuous logging. For example by buffering the data and write it to a file in bulk instead of for each tick a line. Though we need to profile the Logger class to see where the exact bottleneck lies.

Describe alternatives you have considered
Instead of logging in realtime to a file, buffer all data and write this to a file when the world completes.

Additional context

As an alternative, we can also use a seperate thread dedicated to logging, as proposed in #14.
