Match and Filter IP/CIDR support

[brenocss]

Is your feature request related to a problem? Please describe.

For the cases, where we have known list of IPs/CIDRs that I wanted to match or filter to have desired list of IPs/CIDRs to process/scan as output and would be good addition for the project.

Describe the solution you'd like

This can be done by introducing 2 additional CLI flag to accept IP/CIDR to perform said action, for example:

   -mi, -match-ip string[]  IP/CIDR/FILE containing list of IP/CIDR to match (comma-separated, file input)
   -fi, -filter-ip string[] IP/CIDR/FILE containing list of IP/CIDR to filter (comma-separated, file input)

Match IP/CIDR

Display IPs from input that belongs to given IP/CIDR ranges.

$ mapcidr -cidr 192.168.1.0/24 -mi 192.168.1.253,192.168.1.252

192.168.1.252
192.168.1.253

More input examples:

$ mapcidr -cidr 192.168.1.0/24 -mi 192.168.1.0/25
$ mapcidr -cidr 192.168.1.0/24 -mi cidrs.txt

Filter IP/CIDR

Filter IPs from input that belongs to given IP/CIDR ranges.

$ mapcidr -cidr 192.168.1.224/28 -fi 192.168.1.233,192.168.1.234

192.168.1.224
192.168.1.225
192.168.1.226
192.168.1.227
192.168.1.228
192.168.1.229
192.168.1.230
192.168.1.231
192.168.1.232
192.168.1.235
192.168.1.236
192.168.1.237
192.168.1.238
192.168.1.239

More input examples:

$ mapcidr -cidr 192.168.1.0/24 -fi 192.168.1.0/25
$ mapcidr -cidr 192.168.1.0/24 -fi cidrs.txt

Note:

Currently available ip/il cli flag was introduced as part of the feature request in #4 to match the IPs, which is same as m/match feature, as such as per this change ip/il can be deprecated to avoid any possible confusion.
