Chardet error should be caught and rethrown with helpful error message to user saying which file the problem occurred in

I just ran codespell on all python peps with chardet -e. codespell crashed:

$ codespell --write-changes -i3 -C 5 -H -f -e --count -s --builtin clear,rare,names

The chardet error should be caught and rethrown with a better error message for the end user - I don't even know which file it is based on the error message as is!
