HackTool - WSASS Execution
Tightened up the regex because it was catching too some legit cases. The old one was little too broad.

Suspicious Loading of Dbgcore/Dbghelp DLLs from Uncommon Location
Had to dial this back a bit - turns out legit installers also load dbgcore.dll and dbghelp.dll during setup. I have commented out Downloads and Desktop folders since that's where most people download their installers.
WerFaultSecure Loading DbgCore or DbgHelp - EDR-Freeze
This one was also firing on installer files, so I converted the werfaultsecure loading these dlls into a hunting rule instead of an alert.
Changelog
fix: Suspicious Loading of Dbgcore/Dbghelp DLLs from Uncommon Location - remove troublesome locations commonly used by installers
fix: HackTool - WSASS Execution - update regex to avoid mismatching on legitimate cli
update: WerFaultSecure Loading DbgCore or DbgHelp - EDR-Freeze - change it into hunting rule
