encodeToByteArray() fails when applied with primitives

[geomagilles]

for example:

Avro.default.encodeToByteArray(String.serializer(), "foo"))

triggers

Exception in thread "main" kotlinx.serialization.SerializationException: Non-serializable class kotlin.String is not supported by class com.sksamuel.avro4k.encoder.RootRecordEncoder encoder

I lost a few hours with this issue the other day! I tried to encode an enum class as a byte array and got an error of the form Non-serializable class kotlin.Int is not supported by class com.sksamuel.avro4k.encoder.RootRecordEncoder encoder. Would be great to fix this or at least improve the error message. I spent a long time thinking that I wasn't calling the right method to serialize my data...
