unable to export as PNG or JPEG image

[saikrishna-chunchu]

When I try to export the SVG as a PNG or JPEG image, I am seeing the below error. This is happening before I chose the destination file/directory to export the file.

OS: macOS Catalina, version: 10.15.6 (19G2021)

TypeError [ERR_INVALID_ARG_TYPE] [ERR_INVALID_ARG_TYPE]: The "path" argument must be one of type string, Buffer, or URL. Received type object

• In more recent versions of atom showSaveDialog has become async, so the call to it in svg-preview-view.js#L392 needs to be awaited now 🤷 .
• On top of that showSaveDialog's signature changed so now instead the output file path needs to be picked from the filePath attribute.

This means that line 392 with something like this should theoretically fix this issue:

    const dialogOutput = await atom.applicationDelegate.showSaveDialog(`${filePath}.${outputType}`)
    const outputFilePath = dialogOutput.filePath

From my experience with atom adapting the unit test could be a bit of work, but as the exportTo method is already async (for other reasons) it might to prove to be 0 minutes as well.

(don't have the bandwidth to make a PR for this a.t.m. And even if I did - not sure @josa42 would be willing and/ or able to merge it given the project not maintained label in the README)

Thanks, @sverweij.
I made those changes in my machine and used it, it worked.
@josa42, let me if you can merge these changes. I can make PR (for the rest of community).
