Title: Skip data concatenation for z instruction in collapseRepeated

Example path part:

```
-32.5 -82zt0 0zM371
```

It will be stripped to:

```
-32.5 -82zzM371
```

So it will be crashed (with no output) in convertPathData.js::collapseRepeated:

```js
prev.data = prev.data.concat(item.data);
```

Full example to reproduce:

```xml

```
