Dumps a summary of the compressed and uncompressed sizes of various
types of files in each package. Emits one line per package.
Packages must be zipfiles, readable using "unzip".
Example output line:
filesize=642684 all=603288/919304 dex=119529/353815 name="out/App.apk"
filesize: the size of the package on disk
name: the name of the package as passed to $PROGNAME
These fields are presented as <uncompressed bytes>/<compressed bytes>:
all: the sum of all entries in the package
dex: the sum of all "*.dex" entries in the package
