Making pcap handlers shared globally

[Mzack9999]

This PR implements the following changes:

• Global pcap handler with demultiplexed pre-allocated network worker pool via source port (closes Naabu on macos is looping to scan some IP addresses.Only the first 7 or 8 can scans can be successful. #952 and Global singleton pcap handlers #937)
• Scan Shutdown via context (closes No graceful shutdown i.e. no way to stop naabu from scanning except killing the process #698 )
• Adding OnReceive callback on response from target (partially closes results are not displayed at real time #666 )
• Ipv6 is now optional (closes Naabu does not work if ipv6 is disabled on kernel level #914)

[Mzack9999]

• Filter out traffic according to -iv
• Change output behavior to stdout to print from new OnReceive callback instead of OnResponse (real-time results)

[ehsandeep]

• Source IP being scanned randomly
• Panic upon CLT + C press
