Compare the grids of HLS and CDL

[HamedAlemo]

Both HLS and CDL are at 30m spatial resolution.
We need to confirm if they are using the same coordinate system and grid. If not, decide how to project one to the other. Preferably, we should project HLS to CDL as CDL is a categorical data layer and more noise will be added to the dataset if we reproject it.

The outcome of this task should be:

• the final AOI for our training dataset, which can be a subset of the GFM AOI. (the AOI needs to be a multiply of 224 x 224 pixel chips)
• The projection and coordinate system for the training dataset
