Get the module for the current line of a file

[axelson]

Is it possible to expose a public API that will return the Module that corresponds to the current line in the file? (i.e. if there are three modules defined in a file, this API will return the module whose body is on the specified line).

This would be a replacement for ElixirLS calling into ElixirSense.Core.Metadata.get_env:
