Can't subset a TransformedCube

[felixcremer]

I have a cube c, which I transform to dB values via map and when I try to subset it, I get the following error.
When I first subset the cube and apply the dB function afterwards via map it works.

cdB = map(dB, c)
data = subsetcube(cdB, lat=(20.691, 20.69), lon=(-98.687, -98.686))
ERROR: MethodError: no method matching subsetcube(::ESDL.Cubes.TransformedCube{Union{Missing, Float32},4,typeof(dB)}; lat=(20.691, 20.69), lon=(-98.687, -98.686))

This will be fixed by #137.
