release assets from CI

[tcurdt]

It seems like all the work is already done for the CI to upload the release assets.
But there are no release assets to download.
What am I missing?

Would be great if the debs would be available for download.

Debs of releases are on linuxcnc.org (and, with possibly substantial lag, in Debian testing) but a pull request to add them to GitHub releases would be welcome as well.

@jepler mesaflash debs are available on linuxcnc.org? Can you provide a link?
I cannot seem to find them here http://www.linuxcnc.org/downloads/

Cool, that you are open to a PR. I'll see if I can make this happen.
