[clinical] Assign table name based on specific collection needs

[fedorov]

In case of NLST, first table is assigned name nlst_clinical, while it should be nlst_canc (I think).

... in the "nlst" object in the clinical_notes.json file, one would change "tabletypes":[{"clinical": "clinical data"}, ... to "tabletypes":[{"canc": "cancer data"}...

@bcli4d I see that as of v20, this issue remains unresolved.

Will be nlst_canc in v21.
