retrieveData overwrites cache setting of calc function

[robinhasse]

If the list returned by a calc function contains cache = FALSE, no cache file should be written for this calculation. This works well when running this calculation through calcOutput. But if I run retrieveData, the cache setting of the calc function is overwritten and madrat tries to save a cache file for the calc function even though this has been disabled. I guess, this is not intended, right?

You want to disable caching for a calc-Function completely, right? This should be done by specifying cache=FALSE in the return list of the calc function (similarly like it is done here for a read function: https://github.com/pik-piam/mrdownscale/blob/52c475dcd31a408f5bfe031bf9964894da761abe/R/readLUH2v2h.R#L55)

I did precisely this but this was only effective when running the respective calcOutput call. When I ran the calc function through retrieveData -> calcOutput -> calc function with cache = FALSE, madrat still tried to write a cache file.
