Allow speeding up the protein quantification with GPU

[MicheleBortol]

We could allow speeding up the protein quantification with GPU at:

MACSimaXenium/src/xenium_macsima_core_registration/xenium_macsima_core_registration.py

Line 367 in 5692d3c

self.aligned_data = hp.tb.allocate_intensity(self.aligned_data,

We would need to add cupy as an optional dependency. See:
