Is your feature request related to a problem? Please describe.

The following issues are recurring when working with function resample_in_space() of module xcube.core.resampling:

  1. The returned target dataset may have coordinates of dtype float64 while the source or the target grid mapping was float32. Hence the values are no longer exactly the same.
  2. In the case of up-sampling, resample_in_space() takes considerable time to execute although it should be entirely lazy as it is a dask implementation.

Describe the solution you'd like

Somehow address/mitigate the issues above.
