Missed removal of real dtypes

[janden]

Looking through finufft._interfaces, I found that we were supposed to remove the possibility of real dtypes in 2.3:

finufft/python/finufft/finufft/_interfaces.py

Lines 106 to 116 in defdd48

	if dtype == np.float64:
	warnings.warn("Real dtypes are currently deprecated and will be "
	"removed in version 2.3. Converting to complex128.",
	DeprecationWarning)
	dtype = np.complex128
	if dtype == np.float32:
	warnings.warn("Real dtypes are currently deprecated and will be "
	"removed in version 2.3. Converting to complex64.",
	DeprecationWarning)
	dtype = np.complex64

Same applies to cufinufft._plan:

finufft/python/cufinufft/cufinufft/_plan.py

Lines 88 to 98 in defdd48

	if self.dtype == np.float64:
	warnings.warn("Real dtypes are currently deprecated and will be "
	"removed in version 2.3. Converting to complex128.",
	DeprecationWarning)
	self.dtype = np.complex128
	if self.dtype == np.float32:
	warnings.warn("Real dtypes are currently deprecated and will be "
	"removed in version 2.3. Converting to complex64.",
	DeprecationWarning)
	self.dtype = np.complex64

We should probably go back and do this for 2.4 and 2.3.X.
