There are many places to cut some cycles in the bubble calling code:

Use select to select directly to "branchy" nodes (instead of iterating through every node)
Access edges directly (instead of trying every symbol like: https://github.com/mmuggli/cosmo/blob/KMC/cosmo-color.cpp#L136)
Avoid converting between node and edge indexes needlessly

(and more)

Will wait to see the speed when using the new index, as these might be minor changes.
