> Some format plugins that use third party parsers throw errors when they receive compressed input streams from Drill.  This PR proposes to introduce three utility functions to the DrillFileSystem:
> # isCompressed(<path>):  Returns true/false whether the input file is compressed
> # getCodec(<path>):  This method returns the codec of the file if any
> # openDecompressedInputStream(<path>):  Returns an InputStream that should be readable by parsers that read raw bytes.  This method converts the original InputStream to a byte[] first, then returns that via a ByteArrayInputStream.
