compressed files.
This subclass of Uncompressor contains a parameterized
command for doing the uncompression
It has an uncompressFile() function you call to do the
actual uncompression.

The constructor takes the list of filename \a extensions,
which it passes to the base class, and the \a commandFormat,
which it stores locally. The \a commandFormat is a command
template string.

From \a filePath, derive a file path for the uncompressed
