Timezone in annotation has string offset while decoder thinks it is an Int

As per https://opencagedata.com/api#response the field results.annontations.timezone.offset_string is returned as a string. In the declaration for the JSON decoder it is listed as an Int.

@ConfiguredJsonCodec case class Timezone(
    name:         String,
    nowInDst:     Boolean,
    offsetSec:    Int,
    offsetString: Int,
    shortName:    String
  )

Which in turn causes this error:
