global region does not support different resolutiosn

Creating new global_regions fails when prompting dh greater than 0.1, because it provides spatial cells outside the globe range (e.g. 180.1 lon). It has to do with passing to cleaner_range a prescribed end of 179.9lon, 89.9 lat.

@pabloitu is this issue still a problem. i can make a fix before the v0.6.1 release if that's the case.

This issue is partially fixed with #255. After the merge or #270, this

https://github.com/SCECcode/pycsep/blob/d13f74f0c7e44bb10f5d3758392edd8bb1e84796/csep/core/regions.py#L208-L209

should be modified to:

lons = cleaner_range(-180.0, 180.0, dh)[:-1]
lats = cleaner_range(-90.0, 90.0, dh)[:-1]
