Add posibility to sort on any column

[Yanpas]

Problem: I need to filter out all threads that are running on core 6 (CPUNR = 6).

It would be handy if < and > buttons would change sorting column, like in classic top

[Atoptool]

Implementing a sorting possibility for any column would require a major redesign of atop.
Instead, you can use the parsable output e.g. to find all threads running on CPU6, like this:

atop -Zy -PPRC | awk '$17 == 6 {print $5, $7, $8}'

This command line shows for all threads running on CPU6 the current time ($5), the PID ($7) and the command name ($8) for a live measurement. Add the -r flag to produce this output for a recorded measurement (raw log).
