Providing pre-compiled binaries

[paulocoghi]

Hello, Todd!

Since Cyrtal can compile to the most platforms, including Linux, Mac and Windows, I would like to suggest to provide pre-build ktistec binaries to the final users.

This solves two problems:

• There is no necessity to the final user to first install Crystal in order to be able to use ktistec
• Issues like https://github.com/toddsundsted/ktistec/issues/3 can be completed avoided, since there is no more a compilation phase for the final users

This can also be made automatically on every new release (so you don't have to manually compile each time), by using Github Actions and following the official guide.

@paulocoghi solid suggestion!

i do have a dockerized build on docker hub: https://hub.docker.com/r/toddsundsted/ktistec

the hurdle with osx and windows is creating and distributing the builds. with osx i might be able to leverage homebrew or something similar. but i don't have to a windows machine or development environment. my preference would probably be nix, but that might be even more restrictive. :-)

ah, yeah i'll look into github actions. not sure how far i can get on windows, however, without my own hardware.

Regarding Docker, I believe providing the compiled binary is way better, easier and sufficient than providing a docker option.

For me, in my humble view and experience, Docker increases the complexity.

I tried compiling ktistec on a VDS with 1 gigabyte of RAM and failed :(

I wonder how much memory it needs.

Also if I compile it in a Docker container on my Mac, which files should I copy to the VDS to run it.
