Update package XGBoost

See original GitHub issue

Hi, I am trying to load an XGBClassifier model saved in a .json format from an Android app using Chaquopy but I get the following error: com.chaquo.python.PyException: XGBoostError: [21:21:49] xgboost/include/xgboost/json.h:65: Invalid cast, from Null to Array I think that I have spotted the problem, which is the version of XGBoost supported by Chaquopy (1.1.1). Indeed, the latest version is 1.4.2 and the possibility to load models from .json files was introduced in 1.3.0 if I did not misunderstand. Would it be possible to have an update of the package supported by Chaquopy? Best regards.
