META info syntax question/suggestion

[kevinkleine]

Would it be possible to put the META information in a markdown-invisible expression? For instance

[META]: # ({"title":"Home","tags":["overview"],"createDate":1512133049820,"updateDate":1512133049820})

instead of the HTML comment block Hazel uses now, which is visible in standard md viewers:

<!--META {"title":"Home","tags":["overview"],"createDate":1512133049820,"updateDate":1512133049820} -->

Thank you for this piece of software, it is very useful to me!
