Make password optional in decrypt #7

Hi,

Could you make the password an optional input in decrypt.js ? Qpdf actually allows to decrypt a pdf without providing a password, or with a blank string as a password

qpdf --decrypt input.pdf output.pdf

Thanks

Hey there, I have no idea why github didn't notify me of issues in this repo. I've started looking at this issue. Sorry for the delay.

It looks like you need to enter "" as the value for password. See: https://stackoverflow.com/questions/42785645/qpdf-fails-to-encrypt-without-passwords

Regardless, I've added a test for blank passwords to catch this in the future. (And for documentation)

Thanks for the issue and sorry I didn't see this sooner!
