Consider fixing the deb package dependencies when installing

[sgmlguru]

Installed the latest Fusion DB snapshot (1.0.0~20200615135044) on Ubuntu 20.04, kernel 5.4, pretty vanilla Ubuntu install with nothing fancy. The install complained about these missing dependencies:

Unpacking fusiondb-server (1.0.0~20200615135044) ...
dpkg: dependency problems prevent configuration of fusiondb-server:
 fusiondb-server depends on dh-systemd; however:
  Package dh-systemd is not installed.
 fusiondb-server depends on libzstd-dev; however:
  Package libzstd-dev is not installed.

dpkg: error processing package fusiondb-server (--install):
 dependency problems - leaving unconfigured
Errors were encountered while processing:
 fusiondb-server

It wasn't a big deal installing the missing packages manually but I know that deb packages can be made to handle that sort of thing automatically.

Thanks for the hard work.
