Results from comparing XML could be better

Reporting on behalf of a user on Twitter:

Two identical XML files will incorrectly output a ton of text

# graphtage -v
Graphtage version 0.2.1
# keepassxc-cli export ~/Sync/Passwords-20200612_15-09-57.kdbx > 20200612_15-09-57.xml
# keepassxc-cli export ~/Sync/EstatePasswords-20200502_17-26-13.kdbx > 20200502_17-26-13.xml
# graphtage 20200502_17-26-13.xml 20200612_15-09-57.xml
... (lots of colored output)
# diff 20200502_17-26-13.xml 20200612_15-09-57.xml
... (no output because the files are identical)
# head -1 20200502_17-26-13.xml
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>

Here's a simple reproducer:

# cat 2.xml 
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<KeePassFile>
<Meta>
</Meta>
</KeePassFile>
# cp 2.xml 1.xml
# graphtage 1.xml 2.xml
... (it spits out the full content in green and black of the entire file except for the XML header)

Same result here. I'm using sample XML data from:

https://docs.microsoft.com/en-us/previous-versions/windows/desktop/ms762271(v=vs.85)

Simply create two XML files containing the exact same content from page above, run graphtage like so:

graphtage.exe --from-xml --to-xml .\test1.xml .\test2.xml > result.xml

result.xml is an exact copy of the original XML file(s).
