Request new package to be added

[dadreggors]

The atom-asciidoc-preview package was sunset/archived when Atom was sunset. There have been several attempts to bring it into Pulsar and while there is an easy fix to make it work, there is no maintainer ready to own this package.

https://github.com/asciidoctor/atom-asciidoc-preview

The history of getting this work in Pular is here:
pulsar-edit/pulsar#256

and the fix was to add one line here:
https://github.com/savetheclocktower/atom-asciidoc-preview/blob/master/lib/asciidoc-preview-view.coffee#L24

However this user as seen in the comments above does not wish to maintain the package.
