Add the total number of processed bytes per run to the output

[inazr]

Hello humanoids,

when triggering a dbt run the output tells me the amount of processed bytes per model but not the total amount for all models.
If you maintain projects with hundreds of models you do not want to sum up all the numbers manually.

Feature Request:

Add the total number of processed bytes to the output. Something like the image below:

Many thanks in advance!

Best,
Stephan
