[FEATURE] Add Merge For Linux Host Scripts

[ghost]

Is your feature request related to a problem? Please describe. when i try to add multiple hosts, every time replaced with new one and the is no merge for multiple hosts.

Describe the solution you'd like add a function that input multiple host from users and merge them into a unified host file, host installer and host updater must support multiple merge into a unified host file.

Describe alternatives you've considered i have no idea

There are plenty of such projects combining several sources to one hosts file.

I know of at least one stable from @scripttiger

But which lists do you think this project lacks of? for this project aims to collect from several sources, cleaning them from dead hosts and the output one validated hosts file

Thanks @stale bot, but I'd love to keep this in my backlog. I plan to provide a unique Python script which do everything needed.
