Inter-pixel capacitance for MICADO

[oczoske]

This PR includes the InterPixelCapacitance effect in MICADO_H4RG.yaml. The parametrisation and parameter values are taken from Kannawadi et al., PASP 128, 095001 (2016) and are currently identical to those used in METIS (cf. #272). They should be updated when measurements become available.

By default, the effect is not included. To include set opttrain['ipc'].include or !DET.include_ipc to True.

Example:

cmd = sim.UserCommands(use_instrument="MICADO", set_modes=["SCAO", "IMG_4mas"])
mcd = sim.OpticalTrain(cmd)
mcd['filter_wheel_2'].change_filter('block')   # observe dark
mcd.observe()
# without ipc
hdul = mcd.readout(dit=100, ndit=1)[0]
np.mean(hdul[1].data)     # 4199.027
np.std(hdul[1].data)         # 63.902557
# with ipc
mcd['ipc'].include = True
hdul = mcd.readout(dit=100, ndit=1)[0]
np.mean(hdul[1].data)     # 4199.8267      (identical mean)
np.std(hdul[1].data)         # 59.013878       (reduced noise)

Closes #346
