Title: Add else to if statements for fluidic compressor canister stacking

Hi, I'm new to modding here, but with some little programming experience.
Just thought I would note this issue with the fluidic compressor crashing when finishing filling or emptying a canister.
I added else's to the second if statements to prevent trying to reference the input canister stack when it is set as NULL by the previous if statement. This seems to fix it.
