Better support for package_import_declaration in the module_ansi_header

[pdonahue-ventana]

I'm very excited to find this formatter and it seems very promising. I do have a concern that I noticed right away.

I have this input file which uses a non-empty package_import_declaration in the module_ansi_header:

module Foo
  import FooPkg::*;
  import BarPkg::*;
  import GlobalPkg::*;
  import OtherPkg::*;
  (
   input logic  clk;
   output logic something;
  );

endmodule : Foo

The output is:

module Foo import FooPkg::*; import BarPkg::*; import GlobalPkg::*; import OtherPkg::*; (input logic clk; output logic something;);
    
    endmodule : Foo

It seems more reasonable to have each import on a separate line.

Thanks.
