fix PD_AMORPHOUS keys

[rowlesmr]

From COMCIFS/cif_core_multiblock#42 and #275

Insufficient information was recorded to correctly identify the linked PD_PEAK from the PD_AMORPHOUS information.

Added _pd_amorphous.diffractogram_id. Removed _pd_amorphous.phase_id, as an amorphous peak (or any peak) could belong to more than one phase.

@rowlesmr I think it was I who decided to accidentally time travel in my last PR. Just ignore this for now, I will create a separate PR to fix it.

[rowlesmr]

No dramas :)

[vaitkus]

@rowlesmr Should be fixed in master branch now.

@rowlesmr This is a known issue, feel free to ignore it for now. :)

Also, merging this will probably allow for #124 to be closed, as every category will (hopefully) have examples.
