Publish deb package via distribution channels

[jamesmarkchan]

We should publish our .deb installer package in common linux distribution channels.

Ideally we'd love to be able to install it with sudo apt install jdiskmark or sudo apt install jdm

Potential channels:

1. official debian repository (most ideal)
2. official ubuntu repository
3. Ubuntu Software
4. Personal Package Archive (PPA)

@jslcom I thought this would be good for you to do the publishing and @JasmineRRod and I could support in any research and testing that you need. my current experience w the ms store it's pretty clear that publication channels are quite involved. Since we are at heart an opensource project getting a linux distribution channel in place is essential.
