Feature Request: Support for Obsidian tasks (emoji) format

[stengland]

I see you are already supporting tasks with dataview metadata. Would there be any chance of you also supporting the tasks emoji format from the popular Obsidian Tasks plugin?

I think most of the code could be lifted from here https://github.com/obsidian-tasks-group/obsidian-tasks/blob/main/src/TaskSerializer/DefaultTaskSerializer.ts

Would you accept a PR tyring to do this? (I might give it a try in the unlikely event I get some free time to code).

Cheers for the hard work already done 🙏
