This NIP standardizes bech32-formatted strings that can be used to display keys, ids and other information in clients. These formats are not meant to be used anywhere in the core protocol, they are only meant for displaying to users, copy-pasting, sharing, rendering QR codes and inputting data.

These are the possible bech32 prefixes with `TLV`:
- `nprofile`: a nostr profile
- `nevent`: a nostr event
- `nevent`: a nostr event pointer

- for `nrelay`, this is the relay URL
- for `naddr`, it is the identifier (the `"d"` tag) of the event being referenced. For non-parameterized replaceable events, use an empty string.
- `1`: `relay`
- for `nprofile`, `nevent` and `naddr`, _optionally_, a relay in which the entity (profile or event) is more likely to be found, encoded as ascii
- for `nprofile`, `nevent`, `naddr`, `nreq`, _optionally_, a relay in which the entity (profile or event) is more likely to be found, encoded as ascii
- this may be included multiple times
- `2`: `author`
- for `naddr`, the 32 bytes of the pubkey of the event
- for `nevent`, _optionally_, the 32 bytes of the pubkey of the event
- for `nreq`, _optionally_, 32 bytes of one entry in the `"authors"` field, can be specified multiple times
