Fixed KF DPS and attack speed breakpoint calcs

[Bobastic]

Fixes #9424

Description of the problem being solved:

When comparing attack speed breakpoints for KF in PoB vs in game it is noticeable that PoB is wrong. For example, you can "gatling" in game holding right click when PoB tells you that you shouldn't be able to.

The issue is that PoB uses server ticks for KF attack speed breakpoint calcs where they apparently don't matter (see the video in #9424)

Steps taken to verify a working solution:

• I compared the breakpoints I fixed to nemrod's calc https://nemrod10.github.io/KF/
• I can gatling with these values in game but old PoB told me that I couldn't
