JSONCodec.decoder streaming is broken with optional values

[paulpdaniels]

The latest release (1.2.0) breaks the JsonDecoder[A].decodeJsonPipeline operation in cases where there is an optional primitive within an object body.

Consider:

case class Simple(name: Option[String])
implicit val schema: Schema[Simple] = DeriveSchema.gen

ZStream
  .fromChunk(charSequenceToByteChunk("[{\"name\":\"John\"}]"))
  .via(ZPipeline.decodeCharsWith(StandardCharsets.UTF_8))
  .via(JsonCodec.jsonDecoder(Simple.schema).decodeJsonPipeline(JsonStreamDelimiter.Array))
  .runCollect
  .either
  .map(results => assertTrue(results.isRight))

This results in the error Left(value = java.lang.Exception: .name(expected '"' got 'J')). The same error does not occur when the value is required or if you use the assertDecodes utility in the test project, which is backed by JsonCodec.schemaBasedBinaryCodec[A](cfg)(schema).streamDecoder.
