diffoscope can't use busybox gzip

$ diffoscope --html ~/out/diff.html ~/out/1/alpine-rpi-edge-armhf.tar.gz ~/out/2/alpine-rpi-edge-armhf.tar.gz 
gzip: unrecognized option: decompress
BusyBox v1.33.1 () multi-call binary.

Usage: gzip [-cfkdt123456789] [FILE]...

Compress FILEs (or stdin)

	-1..9	Compression level
	-d	Decompress
	-t	Test file integrity
	-c	Write to stdout
	-f	Force
	-k	Keep input files

Tested on alpine, it then hangs, probably diff-ing the raw binary.

I've worked around this locally for now by calling gzip with -d -c.
