extra package needed to install hyperglass

[Mr-Sheep]

Bug Description

When running the curl https://install.hyperglass.dev | sudo bash command, i got few error messages:

The headers or library files could not be found for jpeg,
a required dependency when compiling Pillow from source.

Please see the install instructions at:
   https://pillow.readthedocs.io/en/latest/installation.html

and

no acceptable C compiler found in $PATH

I had to install the package libjpeg-dev and build-essential myself before rerunning the script. I wonder if these two packages can be added to the automatic installation script?

Steps to Reproduce

1. Fresh installed debian.
2. Run the automatic installation script.
