csv_to_fd: improve validation

• Validate flags:
  • Ensure M and V can't occur more than once.
  • Ensure absence of V for vendor 0.
  • Ensure presence of V for vendor not 0.
• Ensure AVP name is unique per vendor.
• Add AVP name to most errors.
• Use csv.DictReader?.line_num for more accurate line numbers.

TODO: enforce M and V must be present once and only once.
Some AVPs currently fail that rule, including:

• RFC 4005 / RFC 7155 QoS-Filter-Rule
• 3GPP TS 29.212 PDN-Connection-ID
• 3GPP TS 29.212 PS-to-CS-Session-Continuity
