noclobber behavior

[mrgleeco]

Describe the solution you'd like
For some usage, it is desired to rerun the template to get updated outputs. However for some files we would rather NOT update. In this case, we want to check if output destination file exists and if so, skip. I would call this optionality like noclobber: [] where a list of template names are conditionally applied.

A quick review of the code does not reveal this feature -but maybe it already does?

Hey @mrgleeco ,

Are you interested in doing the work to develop this kind of functionality?

I would ask that the configuration field be called no_update, as we already have skip_files following snake case, and I think it might be more obvious to people what no_update means.

I'd also like some more design work put in to determine how this would work. Would it be a list of files? Can users supply directories? Would it be better to support globs?
