[iecorrect]: [drop] functionality handles wildcards and [n_obs] incorrectly

Using the following sheet, the command neither respects the intended total number of observations to drop, nor does it correctly implement the logic in the second row (zero observations should be dropped).

make	foreign	n_obs	initials	notes
`*`	1	22
Test	0	0

iecorrect apply using "/users/bbdaniels/desktop/correct.xlsx" , idvar(make foreign)  noi
    No corrections of type numeric.
    No corrections of type string.
    Number of observations to be dropped: 22


** Drop observations 
drop if (foreign == 1)
(22 observations deleted)
drop if (foreign == 0)
(52 observations deleted)

Corresponding correction required at the helpfile below, including indicating whether n_obs is required or not (and whether or not it is required to be accurate -- I would make this check the default, but skippable by entering wildcard * in the cell):

@luizaandrade I just wanted to confirm that we are NOT allowing wildcards in the n_obs column here. Otherwise it now works correctly.

that is correct. this is now also being tested in f2c851f
