pt_options hold options passed to pivot table functions

new_pt_options(pt_filter = NA_character_, pt_row = NA_character_,
  pt_col = NA_character_, pt_metrics = NA_character_,
  pt_sort = NA_character_, pt_sort_order = 1, pt_row_subtotals = FALSE,

  pt_other = NULL)

`pt_filter`	character that is parsed in context of dt i
`pt_row`	character vector - rows to group by
`pt_col`	character vector - columns to pivot and group by
`pt_metrics`	character that is parsed in context of dt j
`pt_sort`	character vecotr used to sort dt
`pt_sort_order`	1 decreasing (default) or -1 increasing. can be vector.
`pt_row_subtotals`	logical - should row subtotals be included?
`pt_col_subtotals`	logical - should column subtotals be included?
`pt_other`	to be implemented
