v0.4.0

What's Changed

• OpenFeature: Contstrain StructureValue to Map[String, FlagValue] by @alexcardell in #36
• OpenFeature: Add Java SDK Provider implementation by @alexcardell in #37
• Add sdk-otel4s module by @alexcardell in #38

Breaking Changes

• The constraint for resolving objects has changed, with a new StructureCodec required. This can be derived from Circe codecs using the Circe module implicits.
• StructureCodec can be defined explicitly, and requires your variant type to be isomorphic to a Structure, which is Map[String, Boolean | String | Int | Double | Structure]
