Make the intensity correction an optional parameter

Description of feature

Hi @CaroAMN,

Here is a suggestion from my colleague Irene Lamberti:
Some datasets do not require intensity correction but only stitching or stitching+alignment, so would it be possible to make the intensity correction an optional parameter?

Thank you,

Tatiana
