Using markdown comments throws NotImplementedError

[TymekDev]

Describe the bug
Using markdown comment throws NotImplementedError. I suspect this is due to the present using these comments as part of it's syntax (for effects and coloring).

To Reproduce
Add a markdown comment (<!-- comment text here -->) to slides file.

Expected behavior
Either not throwing an NotImplementedError exception or throwing a more descriptive one (e.g. informing that comments not being supported).

Slides

# Markdown Comments Test

Text before comment.

<!-- A markdown comment. -->

Text after comment.

Environment

• OS: Ubuntu 20.04.1 LTS
• Terminal emulator: kitty
• Python version: 3.8.2
• present version: 0.5.1

Additional context
A solution for this could be differentiating between a regular comment and present syntax. For example <!-- effect=explosions --> could be a regular comment and <!-- [present] effect=explosions --> could be present syntax.

Thanks for reporting this!

I think all comments can be skipped. Though the style will be applied if a comment has effects and colors in it.
