   [SDAP-481](https://issues.apache.org/jira/browse/SDAP-481)
   
   _(NOTE: Will change PR target once 455 is merged)_
   
   - Enabled internal compression for netcdf match up outputs
   - Upgraded to `netcdf4==1.6.4`. This is required as the compression params 
in `createVariable` are only available in newer versions of this library.

   Tested this locally. Compared the output with the following command output:
   
   ```bash
   nccopy -4 -d 5 ...
   ```
   
   
   Confirmed variables all contain `_DeflateLevel = 5` in the following output:
   
   ```bash
   ncdump -h -s ...
   ```
   
   Vardis also confirmed the outputs look as expected.

   Idea for future improvement -- allow user to specify compression level? This 
is currently set to 5.
