bugfix witk ak and bk for multiple file concatenation

[jeromebarre]

Bug fix when files are concatenated the line changes allow for code not to crash because of index issue.

This was not caught by test that uses only one files as input.

I'll put a note to update testinput with multiple files in the future (too much on my plate right now)...

@jeromebarre do you know why this is failing, should we try an empty commit?

But's it's saying that for intel with the new containers:

The following tests FAILED:
566 - test_iodaconv_tropomi_no2_tropo (Failed)
569 - test_iodaconv_aeronet_aod (Failed)

These two tests started to fail with the new Intel container if I am not mistaken.
