// some notes:
//
// - quoted characters can be in any mixture of lower and upper cases.
//
// - we do not recognize a folding white space (FWS) or comment (CFWS).
// for our purposes, instead, we accept any sequence of Unicode
// white space characters (denoted here to `S`). For comments, we accept
// any text within parentheses while respecting escaped parentheses.
// Any actual RFC 2822 parser is expected to parse FWS and/or CFWS themselves
// and replace it with a single SP (`%x20`); this is legitimate.
//
// - two-digit year < 50 should be interpreted by adding 2000.
// two-digit year >= 50 or three-digit year should be interpreted
// by adding 1900. note that four-or-more-digit years less than 1000
// are *never* affected by this rule.
//
// - mismatching day-of-week is always an error, which is consistent to
// Chrono's own rules.
//
// - zones can range from `-9959` to `+9959`, but `FixedOffset` does not
// support offsets larger than 24 hours. this is not *that* problematic
// since we do not directly go to a `DateTime` so one can recover
// the offset information from `Parsed` anyway.
