Fix Failed to execute 'atob' on 'Window': The string to be decoded is not correctly encoded.

[24min]

privt-js version:1.6.0

//pdf base64 value start with data:application/pdf;base64,
const pdfBase64 = `data:application/pdf;base64,xxxxxxxxx`;

 printJS({
               printable: pdfBase64,
               base64: true,
            })

The above code causes the error Failed to execute 'atob' on 'Window': The string to be decoded is not correctly encoded.

Beacuse atob function can‘t transfer the symbol(,)

So we should remove this symbol.
