Support 0.5 models

[alanocallaghan]

Fairly minimal changes as the updated model spec tries to be transparent, but took the time to replace some deprecated calls.

Adds checks for our stated support (2D images with one input and output)

I was concerned about handling multiple inputs and outputs in BioimageIoTest , but I realise now that:

• you can already have multiple inputs and outputs in 0.4 and we definitely don't handle those
• we would have to completely refactor how classification is done to handle these anyway! (I think... maybe I underestimate the flexibility of DnnModel etc)

I've tested with the broad U-net model and the top 8 models on the model zoo. All of the 2 models work.

Should I be doing something to get the version catalog pointing to a snapshot release...?

Usually no, but you may have to refresh your gradle dependencies if the snapshot was updated recently.
See https://docs.gradle.org/current/userguide/dependency_caching.html

(If it can’t be found at all, maybe we’re missing the snapshot maven repository… but I think it should be there ok)

[petebankhead]

Not sure if it’s relevant but it’s been two weeks since we last updated the main QuPath snapshot jars (and therefore the catalog) - I’ve just started that action manually at https://github.com/qupath/qupath/actions/runs/13164711465

Ahhh of course, yeah that'll be why it's not seeing the recent updates. Thanks!

I would like to solve #10 but I can't identify how the bug occurs and it was an issue with the previous extension also, so am inclined to just merge this.
