Added opportunity to use DICOM tag values as prefix in @hashuid #7

Dear John,

I've got a suggestion for the anonymizer in CTP. Maybe good to first explain our use case. Based on the patient ID, we want to determine the root UID of a data set. Therefore, we've created an extra anonymizer which adds a private dicom tag using the @lookup function. Afterwards, a second anonymizer will perform the regular anonymization, using the value of this private dicom tag to hash the UIDs (using @hashuid(PrivateUidTag, this)).

In this change, I've extended the functionality for the first input parameter (prefix) of @hashuid. Although it's not perfect, it worked in our situation. I'm sending this pull request as you might be interested to implement some similar functionality.
