Convert mixed representation of CPKs (by strings or arrays) to normalized representation (just by arrays).
‘ids` is Array that may contain:
-
A CPK represented by an array or a string.
-
An array of CPKs represented by arrays or strings.
There is an issue. Let ‘ids` contain an array with serveral strings. We can’t distinguish case 1 from case 2 there in general. E.g. the item can be an array containing appropriate number of strings, and each string can contain appropriate number of commas. We consider case 2 to win there.
