Make post space width fill optional

[bzkrouse]

element_block() updates:

• Add option for filling the post-space to the full width of the cell
• remove unused border option

This will effectively close #407 as it should cover most use cases

tested with an example containing multiple groups - works well 😊

my_tfrmt <- tfrmt(
  group = c(grp1, grp2),
  label = label,
  param = param, 
  value = value,
  column = column,
  # testing element_block's fill param here
  row_grp_plan = row_grp_plan(
    row_grp_structure(group_val = ".default", element_block(post_space ="--", fill = FALSE)),
    label_loc =element_row_grp_loc(location = "spanning")
  ),
  body_plan = body_plan(
    frmt_structure(group_val = ".default", label_val = ".default", frmt("xx"))
  )
)

print_mock_gt(my_tfrmt, .default = 1:2)%>%
  tab_style(
    style = cell_text(whitespace = "pre", align = "left"),
    locations = cells_stub()
