ReactiveMongo 0.13.0 incorrectly handles Decimal128

[Daniel Slapman]

Hello. After 0.13.0 update I discovered, that byte order of Decimal128 written by reactivemongo is wrong.

The following code (runnable with ammonite)

The following code (runnable with ammonite)
import $ivy.`org.reactivemongo::reactivemongo:0.13.0`
import reactivemongo.api._
import reactivemongo.bson.buffer.ArrayBSONBuffer
import reactivemongo.bson.{BSONDecimal, BSONDocument}

val bd = BSONDecimal.parse("12.76")

val el = BSONDocument("d" -> bd.get)

val pack = BSONSerializationPack

val buffer = new ArrayBSONBuffer
pack.writeToBuffer(buffer, el)

println(buffer.array.map("%02X" format _).mkString)

prints 180000001364000000000000003C30FC0400000000000000 while BSON corpus gives 18000000136400FC040000000000000000000000003C3000 here

Any thoughts?
