Add NetworkScanner Compound Target Rule and Modifications to SANS_Triage and FTPClients Target Rules

[reece394]

Description

Following on from #999 I decided to create a NetworkScanner compound rule. Additionally, added Robo-FTP to the FTP Clients compound rule and added both NetworkScanner and FTPClients to SANS_Triage due to these being mentioned in the FOR528 Ransomware and Cyber Extortion Poster here
