Fix tiling issue in raster_tile.py

[srmsoumya]

Description

Raster tiler is missing a few tiles while creating the chips. Rounding the profile["transform"] to 3 decimal places is creating the issue of chips overwrite, changing this to 6 decimal places fixes the issue.

@rbavery I was able to reproduce the test errors locally.

The array values are different for tiles in

• tests/data/rastertile_test_fill_nodata_expected/
• tests/data/rastertile_test_fill_nodata_result/

Visually they look similar but array values are different. eg:

We are just changing the precision for file names, everything else remains the same. Is it because we changed from

-  opencv-python>=4.1
+  opencv>=4.5.5

@srmsoumya looking at your recent commit and just a heads up, using opencv appears to be what works for recent releases so I think we should stick to that. See https://github.com/CosmiQ/solaris/issues/461
