Estevão Soares dos Santos af82c2b616 feat(image dimensions): add support for setting image dimensions within markdown syntax
This feature allows users to define the image dimensions using markdown syntax:
```
![my image](img.jpg =100x80 "image title")
```
To enable this feature, use the option `parseImgDimensions`.

Closes #143
