API to register custom functions in DQL

[snsvrno]

TLDR: As a plugin creator I would like to register JS functions from my plugin to be accessible during DQL dataview queries.

I wrote a simple plugin where you can identify key "notes" and have access to them in other files using JS.

A quick example for that plugin would be a project. You can define a md file as the project using a specific metadata key, and then when you are in a note in the same folder or nested down the folder tree you can access the metadata for that file.

I created a global variable (sn) which I can call now in templater and dataviewjs which allows me to access that data (for example, I can get the project name inside an issue for that project = sn.type_project('name'))

I would like to register this function in dataview's query language because most of the time I really just want to make simple queries for lists and don't want to write js code:

TABLE
	sn_type_project("name"),
	title,
WHERE
	type = "issue" AND
	!contains(file.path, "template")

I looked at the API and I don't see a way to do this.

Is there a way to do this currently and is there any opposition in creating a way to allow other plugins to add DQL functions?

If there is interest I can work on it and submit a PR once its implemented.
