Title: have `compile` render api expect the template name

This is so you can provide meaningful backtraces and file information
even when rendering content that has already been rendered by another
engine.

This came up when attempting to implement `compile` for deas-erubis.
It is nice to give a file name so any exceptions get nice backtraces.

@jcredding ready for review.
