Hi. Thanks for the patch! See some comemnts inline.

For exmaple, we can have 'add', 'delete', 'modify' commands in the file, but we don't have a test for this. All cases above have no bands specified. I'm curious how the oneline prints will look with bands, multiple bands per meter and if the code is actually capable of parsing multi-band dumps in a oneline form. That's, I think, the main reason why meter dumps are multi-line.
