//! Parser for FRED-style object replies: CZ.NIC's FRED registry software
//! (.cz and the registries running it: .cr .ls .mk .mw .tz .ve) and NIC.ar,
//! which prints the same layout.
//!
//! The reply is a series of blank-line-separated objects, each opened by its
//! class key (`domain:`, `contact:`, `nsset:`, `keyset:`). Contact and nsset
//! objects carry their own `created:` / `changed:` / `status:` lines, so a
//! flat label scan took a contact's creation date as the domain's and mixed
//! contact statuses in. Domain-level fields are read only from the `domain:`
//! object here; nameservers, registrar and DNSSEC come from the generic
//! parser.
//!
//! Example FRED response (trimmed):
//! ```text
//! domain:       nic.cz
//! registrant:   CZ-NIC
//! nsset:        CZ.NIC
//! registrar:    REG-CZNIC
//! status:       Sponsoring registrar change forbidden
//! registered:   30.10.1997 01:00:00
//! changed:      17.11.2020 14:25:52
//! expire:       15.03.2027
//!
//! contact:      CZ-NIC
//! org:          CZ.NIC, z.s.p.o.
//! name:         CZ.NIC, z.s.p.o.
//! created:      17.10.2008 12:08:21
//!
//! nsset:        CZ.NIC
//! nserver:      a.ns.nic.cz (194.0.12.1, 2001:678:f::1)
//! ```
//!
//! FRED statuses are prose ("Sponsoring registrar change forbidden"), kept
//! whole. Times are the registry's local time without a zone and are read
//! as UTC, like the generic parser does.
