Map calling destructors incorrectly during cleanup (now fixed)

[JacksonAllan]

Unfortunately, there was a bug in previous releases that caused maps to call the wrong destructors during cleanup.

Specifically, the cc_map_cleanup function (invoked via the cc_cleanup API macro) would call the key-type destructor on elements and the element-type destructor on keys. This bug would affect users using destructors in conjunction with maps and typically result in a crash.

I’ve just published a new release (v1.3.2) that corrects this bug. I’ll leave this GitHub issue open for a few days for visibility and then close it.
