Adapt to NumPy 2.0 #26

At least

A new variable-length string dtype, numpy.dtypes.StringDType and a new numpy.strings namespace with performant ufuncs for string operations

Hence

Check for NumPy version >= 2.0 in __init__.py
Use the new string dtype by default?
Keep the old around as char, i.e. Vector.as_char etc.?
Check what missing value to use for strings
Use np.strings instead of np.char where applicable
Allow strings in aggregate.py function use_numba?
