Remarks
This is the numeric-decode half of enum conversion — the equivalent of the Rust crate's
num_enum-derived TryFrom<u8>/TryFrom<u16> impls. It covers
every enum declared alongside it directly in DatabentoDotNet.Dbn except
FlagSet. Publisher, Dataset,
and Venue are wire-validated the same way, but by
PublisherValues rather than here: those three tables are generated
from the dbn crate's publishers.rs, and their validator is generated beside
them so a release bump reproduces both from one source. It answers "is this raw value one of
the discriminants this enum defines", independent of any text form. Rejection here is the numeric out-of-range failure mode; an unrecognized wire
string is a distinct failure handled by WireStrings — upstream keeps
those as two different error types, and this port keeps them as two different call surfaces
on purpose.
Every enum here is strict: an undefined raw value is rejected the same way whether or not
the enum is #[non_exhaustive] upstream — #[non_exhaustive] only affects whether
downstream Rust code can exhaustively match the type, not whether an arbitrary byte is
a valid instance of it. FlagSet is the sole exception among the enums covered
here: every raw byte is already a valid FlagSet, so it has no entry here — use
an explicit cast instead.
Each enum gets its own TryFrom{Enum} method rather than one TryFrom overloaded
by the out parameter's type: overload resolution needs that type before it
can pick an overload, so out var at a call site — the ordinary way to call a
TryXxx method — cannot disambiguate and fails to compile. Per-enum names work with
out var the same way TryParse(string, out int) does.
