get image base64 from nodejs

[joneldiablo]

How could we get the final base64 or buffer instead save the file?

You should be able to get the base64 with the following example:

const f = await filterous
            .importImage(buffer)
            .applyInstaFilter(filterName, options)
const base64 = f.canvas.toDataURL()

Use .save(); //without filename in PR #10
