Allow tp.file.include to accept data to populate a template.

[clearf]

It would be nice to be able to pass data to a template.

For example, I often use a pattern where I'll use the selection from a file as input to a template, which will often require some processing.

What I'd like to do is be able to separate the formatting/output from the data processing. For example, imagine:

Template

Name:  <% name %>
Age:  <% age %>

Base template

<%* 
    let data = {} 
    data.name = tp.file.selection();
    data.age = f() // some complex lookup
    let contents = await tp.file.include("[[test template]]", data);
    
-%> 

output:  <% contents %>  

This doesn't work, because there's no "data" argument to tp.file.include

Instead I end up having to include the formatting of my output within the logic, which is ugly.

<%* 
    let data = {} 
    data.name = tp.file.selection();
    data.age = f() // some complex lookup
    // let contents = await tp.file.include("[[test template]]", data);
    let contents = `Name: $[data.name}
    Age: ${data.age}`
    
-%> 

output:  <% contents %>  

It would be nice if tp.file.include would let us specify some kind of data payload.

e.g., await tp.file.include("[[test template]]", data);

Obviously this is a toy example. Being able to do this would add a lot of flexibility and reduce unnecessary code/template duplication. And who doesn't like that?
