matrix factorization takes a looooooong time

[jakobsarthur]

on a 13th gen intel i7-13700H 2.4GHz a simple lci calculation spends a looot of time factorizing the matrix for a system with ~70ish entries in the timeline, and 3 db's.

on my macbook with m4 chip this was a bit quicker, but also showed a similar pattern where most time was spent factorizing the matrix

@jakobsarthur is this an actual issue of timex of rather of bw2calc? Just trying to clean the issue list up a little

@TimoDiepers that depends on how you see the issue... bw2calc does what it always does, but we're feeding it something it obv struggles with. The question is if we can feed it something different with while keeping the required output.
