[Task] Explore the correct way of creating COG.

[mahrsee1997]

As per rasterio/rasterio#2675 (comment) the way we are creating COG's is not right.

Check correctness & measure efficiency of the current & suggested approach -- make necessary changes if required.

Code snippet as per above comment:

                profile = {
                    'dtype': dtype,
                    'width': data[0].data.shape[1],
                    'height': data[0].data.shape[0],
                    'count': len(data),
                    'nodata': np.nan,
                    'crs': crs,
                    'transform': transform,
                    'compress': 'lzw'
                }
                with tempfile.NamedTemporaryFile() as temp:
                    with rasterio.MemoryFile() as memfile:
                        with memfile.open(driver='GTiff', **profile) as f:
                            for i, da in enumerate(data):
                                f.write(da, i + 1)    
                                # Making the channel name EE-safe.
                                f.set_band_description(i + 1,
                                                    get_ee_safe_name(channel_names[i]))
                                f.update_tags(i + 1, band_name=channel_names[i])
                                f.update_tags(i + 1, **da.attrs)

                            # Write attributes as tags in tiff.
                            f.update_tags(**attrs)
                            print("tags update : " + datetime.now().strftime("%H:%M:%S"))
                            
                            # Create COG
                            rasterio_copy(f, temp.name, driver="COG", compress="lzw", bigtiff="IF_NEEDED")
                            
                            # Copy the created COG to gcs.
                            target_path = os.path.join(self.asset_location, file_name)                
                            gcs_copy(temp.name, target_path)
         
                del f, memfile, data
