We have used fressian-clr cross platform with jvm implementation. We noticed that ToByteArray method in clr Guid class gives the bytes in different order than jvm. This commit makes fressian-clr Guid compatible with jvm UUID.

This is documented in the Guid Structure, see https://msdn.microsoft.com/en-us/library/system.guid.tobytearray(v=vs.110).aspx

In the Remark section:
"Note that the order of bytes in the returned byte array is different from the string representation of a Guid value. The order of the beginning four-byte group and the next two two-byte groups is reversed, whereas the order of the last two-byte group and the closing six-byte group is the same. "
