Eventlogedit-evtx--Evolution

Remove individual lines from Windows XML Event Log (EVTX) files

Support: Win7 and later

Compare with DanderSpritz,my way don't need dll injection and support more version(Server2012 and later).(It can be used to delete the setup.evtx,others may be affected by competitive conditions.)

Need more test and suggestions.

The data structure and some code details are inspired by https://bbs.pediy.com/thread-219313.htm

My posts about the details:

Later I'll translate them into English.

Note:

WinXP and Win7,ObjectTypeNumber = 0x1c
Win8 and later,ObjectTypeNumber = 0x1e
