Memory consumption for proteins needs to be optimised

[skalarproduktraum]

At the moment, rendering especially large proteins consumes a lot of memory. This leads to issues like CI failing, for insufficient memory:

FAILURE: Build failed with an exception.

This is likely a place where some optimisation could happen :)
