Add case method == True in compute_density() in base.py

[Lenoush]

here method can also be a bool :

mri-nufft/src/mrinufft/operators/base.py

Lines 323 to 329 in f5a6ba0

	method: str or callable or array or dict
	The method to use to compute the density compensation.
	If a string, the method should be registered in the density registry.
	If a callable, it should take the samples and the shape as input.
	If a dict, it should have a key 'name', to determine which method to use.
	other items will be used as kwargs.
	If an array, it should be of shape (Nsamples,) and will be used as is.

and here :

mri-nufft/src/mrinufft/operators/base.py

Lines 334 to 336 in f5a6ba0

	if not method:
	self.density = None
	return None

if method :
if nufft.cls has method pipe:
method = "pipe"

Seems to be a reasonable addition, I guess you can handle it :)
