OverflowError on wfdb.rdann()

I am trying to read annotations from NSRDB like this:

>>> import wfdb
>>> wfdb.rdann("nsrdb/16265", "atr")

I keep getting the following error:

OverflowError: Python integer 256 out of bounds for uint8

I am running Python 3.12.7 and NumPy 2.2.0.

A similar issue is already open (#522).

Furthermore, a similar issue is discussed in #493.

I should also mention that i am running WFDB 4.1.2.
