allow for inline ouput using additional pipe param

[larqitos]

Added an additional arg so the user can use the inlineLexer to prevent the output of the p parameter. I'm new to the world of pipes but figured this might be the best way to do it.

So an example with the additional argument would be: [innerHTML]="t.text || t.full_text | MarkdownToHtml:{}:true"

I'm adding this functionality because I am leveraging your functionality in one of my projects and could use it as well.
