[FR] Enable scripting in frontmatter customization

[rbennett0000]

I would like to have different frontmatter metadata depending on the source type (book, article, podcast, etc.). The other customization options support scripting (e.g., {if category=="book"}), would like the same capability extended to frontmatter customization.

I could probably accomplish it using inline fields but then it will be inconsistent with my existing templates.

Can you provide a bit more context?

Given the YAML front matter section in the template (at the bottom), we should be able to do this with document notes or tags on the Readwise / Reader side before exporting into Obsidian.
