New API available: Kotlin and hopefully maybe Java too

I couldn't find an API wrapper that allowed for array-type "param" data, so I wrote one. Errata, suggestions etc. are welcome.

michaelNGV, looks great.

Could you explain, why did you choose to use com.alibaba.fastjson.JSON, not kotlinx.serialization.json.JsonElement?
