Feature request: fail early if there is no satellite imagery for requested area

[strogonoff]

For some locations, images for all bands are entirely black (they still weigh more than 30 MB each though). I assume this is because of unavailable satellite imagery. This could be detected before resources are spent on color-correcting and sharpening🤔

Could you please name a location for which this happens? The 'preview image' is of size in KBs, so we can verify it's contrast/threshold of rgb values to make a decision? That is, before downloading any band data.

@plant99: Black images obtained for -c 114.164317 22.325492 -p; all bands finished downloading successfully (just no contents). This happened for one out of three locations I tried, two in Asia and one in Northern America.

Yes, I should’ve tried the preview first. It looks like this, by the way😱

[plant99]

Oh wow, this is some seriously bad data. Thanks for raising the issue again, will look into this.

^ commit partially fixes it by making preview option set by default.
