Parse dataview metadata

[vanadium23]

Many obsidian users (according to downloads) install the obsidian dataview plugin.
It have a different metadata syntax, that you can check at the documentation: https://blacksmithgu.github.io/obsidian-dataview/annotation/add-metadata/.

Also, we can reimplement python code from ts: https://github.com/blacksmithgu/obsidian-dataview/blob/master/src/data-import/markdown-file.ts

Would love to have this as well. Resolving the dataview queries to their actual value so that vault.get_readable_text outputs the content that the user sees in Reading mode would be really helpful especially for NLP-related tasks.
