show adler32 checksum for file in standarized hex zero filled format
Gfal doesn't print ADLER32 checksums with the zero filled hex format as it is typical for other similar tools like xrdadler32 or dome-checksum
$ echo h > x
$ gfal-sum file://`pwd`/x ADLER32
file:///home/user/x dc0073
$ xrdadler32 x
00dc0073 x
$ dome-checksum adler32 x
>>>>> HASH 00dc0073
