Describe the solution you'd like
I would like to be able to use this as a library within other project. For example, being able tom imporr the pakcage or specific modules and then simply call a function to render an image. Something like this:

from termvisage import function_name

function_name.open('path to image file')

Do you offer an interface for something like this?
