Update the added-counters example to print counters in decimal
rather than hex -- now that it is working...

.SH ADD PERF COUNTER EXAMPLE #2 (using virtual cpu device)

Here we run on hybrid, Raptor Lake platform.

We limit turbostat to show output for just cpu0 (pcore) and cpu12 (ecore).

Here we run on hybrid, Meteor Lake platform.

We limit turbostat to show output for just cpu0 (pcore) and cpu4 (ecore).

We add a counter showing number of L3 cache misses, using virtual "cpu" device,

labeling it with the column header, "VCMISS".

We add a counter showing number of L3 cache misses, using virtual "cpu_core" device,

labeling it with the column header, "PCMISS". This will fail on ecore cpu12.

labeling it with the column header, "PCMISS". This will fail on ecore cpu4.

We add a counter showing number of L3 cache misses, using virtual "cpu_atom" device,

labeling it with the column header, "ECMISS". This will fail on pcore cpu0.

We display it only once, after the conclusion of 0.1 second sleep.
