OverflowError with rdann on LUED annotations w/numpy 2.2

Another area of incompatibility with numpy 2.2 I fear...

If I try

wfdb.rdann('physionet.org/files/ludb/1.0.0/1', extension='atr_ii')

or (for version 1.0.1)

wfdb.rdann('physionet.org/files/ludb/1.0.1/1', extension='ii')

I get:

OverflowError: Python integer 256 out of bounds for uint8

Using the command line rdann works fine, and it works after downgrading numpy 1.26. Seems likely related to #493 ?

Pertinent versions:
wfdb-python == 4.1.2
numpy == 2.2.1 (broken)
numpy == 1.26.4 (works)
python == 3.12

Commencez dans wfdb/io/annotation.py, au niveau de rdann, proc_ann_bytes et proc_core_fields, là où le traceback atteint le dépassement de capacité de uint8. Exécutez les exemples rdann de LUDB avec NumPy 2.2.1 et 1.26.4, puis vérifiez que le chargement des annotations se termine sans OverflowError avec la version la plus récente.
