Update LNS/ONS

Since loki 8.x we don't use the argon encryption hashing anymore because it is way too heavy even on desktop and would just kill mobile. I think it's fine for Session to not support those -- owners who registered them can simply submit an update to the blockchain to update them to the new encrypted value.

how can you tell how the record is encrypted? You can infer it from the length: https://github.com/oxen-io/oxen-core/blob/dev/src/cryptonote_core/oxen_name_system.cpp#L1376

Here's the high-level overview: https://github.com/oxen-io/oxen-core/blob/dev/src/cryptonote_core/oxen_name_system.cpp#L1269-L1278

and the actual implementation is here: https://github.com/oxen-io/oxen-core/blob/dev/src/cryptonote_core/oxen_name_system.cpp#L1401 GitHub
