Provide better examples of Hierarchical tables in the crosstab function

[mahaalbashir]

Using more than one (two or more) rows or columns is throwing an error right now saying that

Error in py_call_impl(callable, call_args$unnamed, call_args$named) :
ValueError: Buffer has the wrong number of dimensions (expected 1, got 2)
Run `reticulate::py_last_error()` for details.

Check for other functions as well (acro_pivot_table, acro_table,...)

This is not a bug, just needs an example of what the syntax needs to look like

Need an example to explain that if you want multiple columns or rows you have to pass them as a list then it works properly:

mycols = data[, c("parents")]

table

Produces:

and R output is

But when you do hierarchies in rows not columns the R output is not as nice:

mycols = data[, c("parents")]
myrows =list(data[, c("social")],data[,c("finance")])

table = acro_crosstab(index=myrows, columns=mycols)

table

produces:

but in Rstudio the actual table has no row labels:
