Investigate missing artist types

[szc126]

For example:

• vocal renderer: #vocadb-general, 2020-02, #vocadb-general, 2023-12, #vocadb-general, 2025-05, #vocadb-general, 2026-08, https://vocadb.net/S/555
  • current alternative: Voice manipulator/Other
• photographer: #vocadb-general, 2021-11, #vocadb-general, 2023-08
  • current alternative: Illustrator
• calligrapher/writer: trusted, 2026-08
  • current alternative: https://vocadb.net/T/13358/handwritten-lyrics
• motion capture source (dancer): #vocadb-general, 2024-07

Intuitively I would say that vocal renderer and photographer probably make sense to add, but I am not sure about calligrapher and motion capture source/dancer. I think a requirement before adding them would be to create a tag and get proper numbers/stats to justify an addition.
