Feature: support local image

[ahuigo]

I found it does not support local image:

![local_image](/img/test.png)

It does, but I think you need to remove the first /. Try with ![local_image](img/test.png) and it should work.

I think it's reasonable to support image with / prefixed path(which basePath is ${projectRoot}).

1. By default, vscode markdown preview could load such a image path: ![local_image](/img/test.png).
2. My blog's markdown use such image path too.

Could you support it?

It doesn't make much sense to remote the forward slash, that will break the preview and also as @ahuigo said it will break the blog markdown path.

I think the problem is that this plugin does not support local files at all, I tried removing the forward slash and same outcome.

Take a look at #141 it might help you. I was able to preview correctly on vscode, print to pdf, and view correctly on github. The thing to watch out is the path in relation to the md file.

I'm favor of the request from ahuigo. / prefixed path is accepted by Markdown Preview. It's useful to allow moving md files in the directory tree leaving the image file path unchanged.
