Bug when calculating scpdsi

[aniyou1]

hey, I have been using this library for some time now. I am very grateful to the author for developing this library.
Recently, when I was using this library to calculate scpdsi, I encountered this problem:

Traceback (most recent call last):
File "test.py", line 127, in
scpdsi_feedback_1[:,i,j,:] = indices.scpdsi(precip_time_series=PREC_feedback.values[i,j,:],
/climate_indices/palmer.py", line 525, in _cafec_coefficients
alpha = _cafec_coeff_ufunc(ET_bar, PET_bar)
File "/.local/lib/python3.8/site-packages/numba/np/ufunc/dufunc.py", line 190, in call
return super().call(*args, **kws)
numpy.core._exceptions.UFuncTypeError: ufunc '_cafec_coeff_ufunc' did not contain a loop with signature matching types (<class 'numpy.dtype[float64]'>, <class 'numpy.dtype[float64]'>) -> None

I am using a version prior to 2.0.0. It seems that the subsequent versions do not directly output the scpdsi?

I` tested versions 1.0.10 to 1.0.13 and found that the same problem occurred in all of them. And even though I attempted to adjust the format of the input parameters, it still didn't solve the issue (float 32 or float 64).

The Palmer indices provided in this package are experimental and not recommended for proper climate research.
