Determine whether a TSV cell is a missing value: empty or n/a once any leading or trailing blank, tab, line feed
or carriage return is removed.
Used for the HED column and in assembly, where a cell such as n/a is missing, as hedtools reads it. A padded
value in a column with HED annotations never gets this far: it is reported as TABULAR_INVALID first.
