Revert "Revert "Remove UIManager dependencies from Compression.""

[guillep]

Rework of #16068 by @hernanmd .

The original PR broke the build. But this is going to get fixed :)

[hernanmd]

Can you comment what's the core change?
Because I tried to add in BaselineOfBasicTools:

		spec package: 'System-Spec' with: [ spec requires: #('NewTools-Core') ].

But that raised another error Error: Name not found: NewTools-Core while loading the Baseline

[hernanmd]

I re-take this PR here: pharo-spec/NewTools#683, they're essentially the same changes, but with reduced dependency to SpApplication, it is simpler to check and does not use the System-Spec approach.

So I think this PR can be closed if you agree.

I don't understand the question, could you rephrase?
Do you mean why reverting fixed the build?

Adding the requires clause does not fix the issue, it just adds a new one.
Each baseline only sees what's defined in itself, and in this case BaselineOfBasicTools does not define 'NewTools-Core'
