switch IMGCIF and MULTI_BLOCK import order

[rowlesmr]

see (3) in COMCIFS/cif_multiblock#42 (comment) and COMCIFS/cif_multiblock#43 (comment)

Order change ensures that MULTIBLOCK is defined before CIFIMG, making sure that CIFIMG doesn't override anything in MULTI

@rowlesmr, @jamesrhester Is there any specific reason why _diffrn_detector.id should have the Text content type instead of Code?

Is no, then the content type in the multiblock dictionary is at fault here and the _diffrn_detector.id definition in that dictionary should be changed.

wait out. All of my local copies were stale compared to github

[jamesrhester]

It should be Word as the mmCIF/PDBx type is code, which is case-sensitive no whitespace.

[rowlesmr]

so mmCIF/PDBx type case-sensitive no whitespace == code, which is DDLm

Word
;
         Case-sensitive sequence of CIF2 characters containing no ASCII
         whitespace.
