When I use this library with my scala project, below Exception occurs. It seems that it occurs when I try to deserialize a value of BigDecimal serialized by Messagepack.

I have already found that the workaround is to fix getText in MessagePackParser.java(msgpack/msgpack-java) like below.

But I know that there is another workaround to solve it. It is to fix deserialize in ScalaNumberDeserializersModule.scala(FasterXML/jackson-module-scala) like below.

Therefore, I want to hear you which repositories I should send PR. Thanks.
