added new tasks to the CLI

[Lucrezia-Cester]

Two tasks were added by Yassine:

1) ACR_spatial_res and 2)acr_slice_thickness.

They both run correctly, however they didn't show up in the CLI so when someone types hazen --help they are not included in what the docstring prints out.

I have now added these.

@heyhaleema, could you please check this out?

@YassineAzma added them.

GitHub copilot complained they weren't there but for some reason I had decided they shouldn't be added in this PR specifically.
