[Feature request] Full Ada language support

**Is your feature request related to a problem? Please describe.**

My feature request is specific to the needs of people learning the Ada programming language for the first time (And yes, this is a group of programmers that exists still!). There is currently a drought of software able to properly support Ada. Among the software that *can* do so, are outdated, buggy implementations of IDEs (GNAT/GPS), or methods that take too much hassle to work (Eclipse). Visual Studio Code is the closest to a seamless experience for the language I've experienced, only to find that some programming-related setup was required (A turn-off for many users!).
I was successfully able to compile and run the closed source gnatmake in your extension by loading it in the package.json file and setting the string for .adb files to: ```"cd $dir && gnatmake $fileName && $dir$fileNameWithoutExt"```.
However, this isn't sufficient, as the output terminal is frozen as read-only, and terminal input is required for some applications.

**Describe the solution you'd like**

As the title suggests, I'd like to see full Ada support in this compiler/runner, since there's no real cross-platform means of compiling and running Ada code. If nothing else, a way that someone can point me to set up compiling and running Ada code the way I (and others) use the language. I've searched in the forums, and I saw nothing in regards to the Ada language. Therefore I feel this request is appropriate.

Thanks!
