Comment (by mikeperry):
Notes on v3 HSDesc codepaths:
- We probably want to add our field in the superencrypted section. The
spec says this may be extended.
- v3 descriptors are built via `hs_desc_encode_descriptor()`, which calls
`desc_encode_v3()` via a table lookup
- The superencrypted stuff is done in `encode_superencrypted_data()`,
which builds the fields in `build_secret_data()`
- Decoding on the client side happens via `hs_desc_decode_descriptor()`,
which calls down to `desc_decode_encrypted_v3()`, and then
`hs_desc_decode_superencrypted()` and `hs_desc_decode_encrypted()`
