AHGuncompress Macro - Character Retention

This macro implements a 'Keep' logic using two nested COMPRESS functions. The internal compression removes desired characters from the source string to isolate unwanted characters. The external compression then uses this result to remove these unwanted characters from the source string, leaving only the target characters.
