Add more verbose error message(s) to explain how to rectify dimension order problems

[monocongo]

Is your feature request related to a problem? Please describe.
When the input dataset has variables with dimensions not in the expected order (lat, lon, time) the current behavior is to give an error message that is informative but not prescriptive of a solution:

ValueError: Invalid dimensions for variable 'ppt': ('time', 'lat', 'lon')

Describe the solution you'd like
We should augment this error message with verbiage that indicates how the data can be fixed, i.e. by re-ordering the dimensions using NCO or other tools. For example:

Please use NCO or other NetCDF manipulation tools to re-order the dimensions for the variable as (lat, lon, time). 
For example, using the NCO `ncpdq` operator, like so: `ncpdq -a lat,lon,time in.nc out.nc`

Describe alternatives you've considered
A clear and concise description of any alternative solutions or features you've considered.

Additional context
Issue #548 is a good example of why this is needed.
