feat: allow resource path to be set in connection URI (#134)
feat: allow resource path to be set in connection URI (#134)

Please note that this implementation differs from the JS one, where the
resource path is the namespace you want to reach:

```js
const socket = io("https://example.com/my-namespace", {
  path: "/my-custom-path/"
});
```

Here, we will have:

```C++
sio::client h;
h.connect("https://example.com/my-custom-path/");
h.socket("/my-namespace")->emit("hello");
```
