[FR] Stylesheet export?

[Bluemoondragon07]

Thank you so much for Callout Manager! I have an idea to improve the plugin: stylesheet export.

It'd work like this:

1. Push an Export as Stylesheet button.
2. The plugin generates CSS code for each callout that meets the following critieria:
   1. The callout does not originate from Obsidian already.
   2. The callout does not originate from a theme.
   3. The callout does not originate from a snippet.
3. After the processing finishes, a modal pops up with the CSS, which can be copied.

Just an idea that popped into my mind. Thank you again for this amazing plugin and all the work you put into it. God's blessings!
