Just hit pangeo-forge/pangeo-forge-recipes#275 again and am trying a new if/else statement to not provide a dynamic chunking function at all if we work on a single file. This assumes that we want a single chunk per file, which might be really bad if we work on larger files. So maybe this needs a more thorough solution. Lets see if this works

This did not help unfortunately.

Trying to extend the if/else to the concat_dims input. Fingers crossed
