New #

• @PrefKey(String key) — field-level annotation to override the SharedPreferences storage key. Added @Target({TargetKind.field}).
• @PrefDateTime(DateTimeEncoding encoding) — field-level annotation to specify how a DateTime field is encoded in storage. Added @Target({TargetKind.field}).
• DateTimeEncoding enum — two variants: millisecondsSinceEpoch (stored as int) and iso8601 (stored as String).
• generateInterface parameter added to TypedPrefs — when true, the generator also produces an abstract {ClassName}Base interface.

• Added @Target({TargetKind.classType}) to TypedPrefs — misuse on non-class declarations now produces an IDE-level error
• Added meta as a dependency
• Improved class-level documentation (documents the _ prefix requirement)

• Fixed supported platforms

• Added example file

• Initial stable release.
• Provides the @TypedPrefs annotation with the optional async boolean parameter to control the generator's output mode.
