FloodScan - raster-stats summary min/max missing

[zackarno]

I tested 5 random dates between old and new pipeline and the file values seem to be exactly the same which is great!

One thing i noticed was that the print out of the new pipeline files does not include any pixel summary stats. I think this is actually true for all rasters coming out of this repo and has to do w/ the way the COGS are being written. You can see in the code snippet below that all we see is ? for min/max.

class       : SpatRaster 
dimensions  : 1080, 1080, 3  (nrow, ncol, nlyr)
resolution  : 0.08333333, 0.08333333  (x, y)
extent      : -30, 60, -50, 40  (xmin, xmax, ymin, ymax)
coord. ref. : lon/lat WGS 84 (EPSG:4326) 
sources     : aer_area_300s_20210313_v05r01.tif  
              aer_area_300s_20210313_v05r01.tif  
              memory  
varnames    : aer_area_300s_20210313_v05r01 
              aer_area_300s_20210313_v05r01 
names       : OLD PIPELINE, NEW PIPELINE
min values  :            0,           ?          
max values  :            1,           ?         

It's not really a make or break feature, but they can be a pretty handy way to quickly check the data exists and raster is read in properly - also it' odd that this metadata is not present as it's standard with most cogs (this is the first time i've seen it missing).

@hannahker and I will look into this together and see if it can be added eventually to our pipelines.
