Drives a FIFFLIB::FiffStream through the nested FIFFB_MRI / FIFFB_MRI_SET / FIFFB_MRI_SLICE block hierarchy declared in the header. For each slice it writes the geometry tags (FIFF_MRI_WIDTH / FIFF_MRI_HEIGHT and their metric counterparts), the slice\u2192MRI coordinate transform, the pixel-encoding selector, and the raw pixel buffer in the source's native FIFFV_MRI_PIXEL_BYTE / _WORD / _FLOAT encoding so reads through the FIFF toolchain reproduce the original sample-level data without quantisation drift. Ported from save_slices() / write_slice() in MNE C write_mri_set.c by Matti Hamalainen.
