Passing kwargs to CellService.execute_mdx_dataframe_pivot

[bdunleavy22]

Describe the bug
Cannot pass any key word arguments to the function "execute_mdx_dataframe_pivot" in CellService.

To Reproduce
try to pass a keyword argument to "execute_mdx_dataframe_pivot". For example, tm1.cells.execute_mdx_dataframe_pivot(mdx, cell_properties=["FormattedValue"])

Expected behavior
No Error, keyword argument gets interpreted and returns the result with the given keyword.

Version
TM1py 2.0.2
TM1 Server Version: 11.8.02200.2

Additional context
Seems like an easy fix of adding ", **kwargs" to the arguments of the function, and to the "return self.extract_cellset_dataframe_pivot(
cellset_id=cellset_id,
dropna=dropna,
fill_value=fill_value,
sandbox_name=sandbox_name)" of the function

I do not know whether this belongs here, but execute_mdx_dataframe_pivot fails if two or more hierarchies from the same dimension are being put on the same df axis. To be precise:

The function CellService.extract_cellset_dataframe_pivot uses dimension_name_from_element_unique_name to extract each row/column name which fails e.g. in the case of hierarchy_unique_name containing [abc].[x] and [abc].[y] (both hierarchy names are simoultaneously being simplified to abc).
