Support for XML and XPath and numpy/pandas libraries

[DavidBuzatu-Marian]

This PR contains the changes for integrating numpy/pandas methods natively in RumbleDB. It also expands the data model to include XML data types

Hi David, it looks like one test is still failing, specifically src/test/resources/test_files/runtime/numpy_lib/jsoniq_numpy.jq.
In the boolean column the describe function returns

• count 6 and unique 3 in regular RuntimeTests
• count 4 and unique 2 in RuntimeTestsNoParallelism
  and if I see correctly it should always be 4 and 2. Do you have time to fix this? Your branch has now been merged in the gitlab and we plan to include it with my spark3.5 features in a future release when spark 3.4 is discontinued 😄
