Doc the units when giving size from analysis

[ben-spiller]

It's not 100% clear whether all the sizes reported by the tool are in bytes or kB.

Maybe the generated analysis output text files could include units e.g.
=== All extensions by reverse size ===

• Format: unpacked size, packed size, date deleted, extension name

• Format: unpacked size bytes, packed size bytes, date deleted, extension name

Yeah, all sizes are in bytes; fixing up the docs would make sense.
