Neither of the SparseWriter users actually _wants_ the underlying
WriteSeeker to be closed; so, don't.
That makes it clear where the responsibility for closing the file
lies, and allows us to remove the reliance on the destinations
reliably returning ErrClosed.

Added some tests to verify that files extractions works
with different compression format.
Created a decompressor interface with 2 main methods:
reader(): returns an io.Reader for the specific compression algorithm
copy(): extracts the compressed file into the file provided as param
Created 5 decompressor types:
- gzip: extract gzip files
- xz: extract xz files
- zip: extract zip files
- generic: extract any other file using github.com/containers/image/v5/pkg/compression
- uncompressed: only do a copy of the file
Minor fix to the progress bar instances: added a call to bar.Abort(false)
that happens before Progress.Wait() to avoid that it hangs when a bar is
not set as completed although extraction is done.
