log1p return matrix

[Intron7]

What kind of feature would you like to request?

Additional function parameters / changed functionality / changed defaults?

Please describe your wishes

I think it would be good also in light of pp.scrublet to have the option that log1p returns the matrix and not a copyed anndata. This would save memory.
