More logs

[IITII]

We need more logs when compress failed. But there are no change when I set verbose to 9.

caesiumclt -e -S -R --width 3000 -O bigger -q 70 --threads 11 -o . .
# from help
caesiumclt -e -S -R --width 3000 -O bigger -q 70 --threads 11 --verbose 1 -o . .
# try like unix style
caesiumclt -e -S -R --width 3000 -O bigger -q 70 --threads 11 --verbose 9 -o . .

OK, I see the addi logs when compress without any exception,,,
But we still need more logs like print file absoulte path when exception thrown, then we can handle bad file one by one instead of try all files one by one.

That is why we need verborse logs.
