User power of 10 units in the code

I have identified several places where units of power of 2 (1024) are used to multiply various values while the code is talking about unit of power of 10:

pcvlado /home/vlado/git/CTA/CTA-main > grep -Fri '1024 * 1024' *

We should decide what units should be CTA using and stick to that.

There is a difference between using the units with power of 10 and 2. See these articles:

• https://en.wikipedia.org/wiki/Byte#History_of_the_conflicting_definitions
• https://www.iec.ch/prefixes-binary-multiples

Please do not mix this with other values, where we decided that BYTES should be used.
