Adds spherical harmonics distributed model to MC approach.

[rutgerfick]

• Adds SD3SphericalHarmonicsDistributedModel to use in MC-models.
• Allows optimization of kernels given fixed spherical harmonics coeffiients.
• Removes fit_s0_response function on MC-SH models - the responses are just used if you give them, no reason for double interface.
• fixes MC-SH predict function.
