frontend: Fixes verific import around range order
Test Case
```
module packed_dimensions_range_ordering (
input wire [0:4-1] in,
output wire [4-1:0] out
);
assign out = in;
endmodule : packed_dimensions_range_ordering
module instanciates_packed_dimensions_range_ordering (
input wire [4-1:0] in,
output wire [4-1:0] out
);
packed_dimensions_range_ordering U0 (
.in (in),
.out(out)
);
endmodule : instanciates_packed_dimensions_range_ordering
```
```
// with verific, does not pass formal
module instanciates_packed_dimensions_range_ordering(in, out);
input [3:0] in;
wire [3:0] in;
output [3:0] out;
wire [3:0] out;
assign out = { in[0], in[1], in[2], in[3] };
endmodule
// with surelog, passes formal
module instanciates_packed_dimensions_range_ordering(in, out);
input [3:0] in;
wire [3:0] in;
output [3:0] out;
wire [3:0] out;
assign out = in;
endmodule
```
