Don't crop when there is no data

[jhkennedy]

4612/4636 AutoRIFT job failures in the last two weeks are because they are attempting to crop a data file with no valid data, resulting in an error that looks like this:

Traceback (most recent call last):

ValueError: zero-size array to reduction operation minimum which has no identity

Scenes with no valid data will end with the suffix P000.nc, where P000 represents the % valid pixels in the scene.

You can reproduce this failure by running this from the development branch:

hyp3_autorift LC09_L1GT_209113_20240325_20240325_02_T2 LC09_L1GT_209113_20230915_20230915_02_T2

and show it's resolved by re-running from this branch.

This PR

This PR looks at the file name for the uncropped file and only crops if there is a non-zero % of valid pixels. Otherwise it uploads the file as-is

(ITS_LIVE had been uploading them before we added cropping to mark "successfully processed" so those scenes wouldn't get re-processed).

This PR also:

• drops the ASF naming scheme because we've never used it, resulting in simpler logic
• moves everything in .io to .utils to prevent shadowing the builtin io and make flake8 happy
• moves thumbnail creation inside process next to the browse image creation
