Global.deserialize method

[SethDusek]

Add a versioned method to interpreter to deserialize typed object from raw bytes. Examples:

{
    val ba = fromBase16("028a5b7f7f7f7f7f7f6c");
    val b = Global.deserialize[BigInt](ba)
    b == byteArrayToBigInt(ba)
}

{
    val ba = getVar[Coll[Byte]](21).get
    val prop = Global.deserialize[SigmaProp](ba)
    prop
}
