Parser now outputs placesOfDetention.csv, which contains a list of unique Places of Detention values attached to prisoners (i.e. if two prisoners have the same Place of Detention value, it is only listed once).
Fixed merge conflict in outputting placesOfDetention and prisonerSubtypes.
Combined different placeOfDetention values that are identical in reality.
Sorted placesOfDetention output alphabetically and removed 'Not Listed' from list.
Changed placeOfDetention value 'Gobustan Prison' into 'Gobustan Closed Prison'.
