Upgrade xgboost to 1.3
Description
work started by but was not finished because of regression in XGB Performance on extermely sparse datasets (cox2 perf tests)
for cox2-small scoring this was mitigated with limiting native scoring to 1 thread
however training with full cox2 datasets is still much slower than with 1.2
