Bug fix in masked_loading ROI table reading in case that obs label ID is string of a float

[nrepina]

fractal_tasks_core/masked_loading.py line 112 assumes that the label ID is stored as a string of an integer (e.g. '1') in ROI table obs, however this might not be the case. The Cellpose task output indeed stores label ID in this format, but the RDCnet task stores as a string of a float (i.e. '1.0'). Thus table reading of an RDCnet output table throws the error below (see traceback below).
Tldr; int('1') = 1, whereas int('1.0') = ValueError: invalid literal for int() with base 10: '1.0'

To generalize, recommended fix is to change lines 112 to:

label_value = int(float(ROI_table.obs[column_name][ROI_positional_index]))

Traceback:
