Feature: Search using CIDR mask

[joswr1ght]

RITAv5's search feature allows us to filter the display using several parameters, including src and dst IP addresses. However, we cannot filter by a network subnet to identify other hosts in nearby network ranges.

Feature request: Allow search to accept src and dst parameters using a single IP or a network number using CIDR notation.

For example, in this RITA session, 52.226.139.185 is a high severity finding. One of the questions we should investigate is if there are other hosts with similar IP addresses, possibly in the same /24. RITA does not allow us to answer that question without manually inspecting each of the listed entries.
