Native time function?

[superphiz]

Could you wrap the treegen in a native time function to let the user know how long the generation took? Bonus points if it gave a report:

Calculating collateral rewards took 20 seconds
Smoothie Pool calculation took 16 minute 40 seconds
The total tree generation time on your i5-12900k took 31 minutes, 9 seconds

Sure, as a temporary measure you can prefix the call with time, e.g.

time treegen -e ... -b ...

That will run a Linux command that reports how long the whole thing took once it's done.
