Incorrect escaped character handling

Several escaped double-quotes break the extension. Example json:

```json
{"kek":"\": \"\"\n> },\n> "}
```

here extension works fine up until column 22 (i.e. it breaks at `},`)

Here is the faulty line: https://github.com/richie5um/vscode-statusbar-json-path/blob/master/src/jsonPathTo.ts#L127 - this needs `continue` after incrementing
