Allow passing override parameters in hydromt.raster.full_like

Kind of request

Changing existing functionality

Enhancement Description

It would be great if in hydromt.raster.full_like you can pass alternative parameters, similar to np.full_like: https://numpy.org/doc/stable/reference/generated/numpy.full_like.html

Use case

Freqently, I want to make a new hydromt raster similar to another, but with for example another data type. I am now doing this using hydromt.raster.full, but it would be more efficient and clean when I could use hydromt.raster.full_like.

> old.dtype
np.float32
> new = hydromt.raster.full_like(old, dtype=np.int32)
> new.dtype
np.int32

Thanks for the suggestion @jensdebruijn! This is very well doable I think. Feel free to open a PR for this yourself. Otherwise we are also happy to pick this up ourselves, but likely not before the end of the year.

I suggest to improve the raster.full_like method with two new arguments

• [ ] dtype=None (see numpy.full_like) change dtype if not None
• [ ] fill_value=None (actual fill_value similar to np.full_like). The current nodata value will than be used to set the meta data only with raster.set_nodata. If fill_value one or nodata is not provide we assume these are the same (current behaviour).
