I've just added SIMD support to hipjson since I thought it could 
go even faster. For the the target JSON generated with, I got up 
to 1.8GBps of parsing speed (and recall that the string memory 
are still being copied. With some tests, borrowing memory could 
go up to 3GBps) :
```d
import std.stdio;
void main()
{
     import std.file;
     string data="{";
     string str = 
"https://www.example.org/https://www.example.org/https://www.example.org/https://www.example.org/https://www.example.org/https://www.example.org/https://www.example.org/https://www.example.org/https://www.example.org/https://www.example.org/https://www.exampl";
     foreach(i; 0..1000_000)
     {
         import std.conv:to;
         if(i != 0)
             data~=",\n";
         data~= "\"hello"~i.to!string~"\": \""~str~"\"";
     }
     data~= "}";

     std.file.write("hello.json", data);
}
```
