Don't throw exception of built-in types

[GabrielDosReis]

During the review of #30 , @menuet correctly observed there is existing code that violated Core Guidelines E.14. That should have been caught before it was checked in. Upon further logic inspection, it looks like that the Reader constructor was detecting too late an erroneous condition. Move that detection earlier, at the very minimum, at the site of the Reader object construction.

I am facing the same issue discussed in #30.

This is the very simple code I used:

#include <iostream>

int main() {
    std::cout << "Hello world" << std::endl;
    return 0;
}

And I slightly modified the exception handling in ifc-printer to be able to debug:

--- a/src/ifc-printer/main.cxx
+++ b/src/ifc-printer/main.cxx
@@ -140,8 +140,8 @@ int main(int argc, char** argv)
         for (const auto& file : arguments.files)
             process_ifc(file, arguments.options);
     }
-    catch (...)
+    catch (const std::exception& ex)
     {
-        translate_exception();
+        std::cerr << ex.what() << std::endl;
     }
 }

This is the stack trace in case it helps to fix the issue:
