Fix tqdm crash in TARGET (#116): route progress through QgsProcessingFeedback

[jixuan-chen]

Fixes #116.

tqdm writes its progress bar to sys.stdout, which QGIS sets to None when the Python console is not open, crashing with AttributeError: 'NoneType' object has no attribute 'write' (and the same for the logging calls in the same run).

target-py 0.2.0 adds an optional feedback parameter to Target(...) that routes progress through a QgsProcessingFeedback/QgsFeedback object instead of tqdm when one is provided. This wires it through in target_algorithm.py.

Requires target-py>=0.2.0. Companion PR bumping the version pin in umep-reqs: UMEP-dev/umep-reqs#15

Tested locally on QGIS 3.40.5 (macOS) by running the TARGET algorithm through the actual Processing Toolbox GUI with target-py 0.2.0 installed.

This seems to fix the tdqm issue but I get another error when trying it on my windows 11 machine using our tutorial data. @jixuan-chen , can you see where the error might come from? Some version conflict in pandas (i have 3.0.2)

I fixed the issue above in this pr (jixuan-chen/target#17). I will merge this PR and then wait for you to make a new target-py version
