Add warning when multi-thread decompression is requested (#3208)

Browse Source 
When user pass in argument for both decompression and multi-thread, print a warning message
to indicate that multi-threaded decompression is not supported.

* Add warning when multi-thread decompression is requested
* add test case for multi-threaded decoding warning
   Expectation is for -d -T0 we will not throw any warning,
   and see warning for any other -d -T(>1) inputs
