Fix a bug with asynchronously loaded sounds and ranges and looping.

The issue with this one is that it was possible for the asynchronous
loading process to override settings that were explicitly set via
ma_data_source_set_*(). The fix for this is to only set these on the
asynchronous side if the values in the resource manager's data source
config is not equal to defaults.

-        Make sure the looping state is set before returning in order to handle the case where the

+        The resource manager supports the ability to set the range and loop settings via a config at
+        initialization time. This results in an case where the ranges could be set explicitly via
+        ma_data_source_set_*() before we get to this point here. If this happens, we'll end up

+        default values, we can assume the user has set the range and loop settings via the config. If
+        they're doing their own calls to ma_data_source_set_*() in addition to setting them via the
