Cannot set `marked` options

[jacobmarble]

First

Thank you. This is a great presentation tool.

Problem

I would like my straight quotes to be converted to curly quotes.

However, this frontmatter doesn't convert the quotes:

---
theme: white
...
markdown:
  smartypants: true
---

Proposed

The marked Markdown parser has option "smartypants", and there are other useful options.

• Advanced Slides depends on reveal.js to render slides
• reveal.js depends on marked to convert Markdown to HTML
• marked has a bunch of advanced options
• Advanced Slides forwards frontmatter options to reveal.initialize()
• Advanced Slides should forward the markdown option to reveal.js

Perhaps the markdown key needs to be added here? https://github.com/MSzturc/obsidian-advanced-slides/blob/73c38f8627a14574ad6f0b52b7e5028b3081971f/src/yamlParser.ts#L38-L99
