[Issue] Filtered IPs should not show up in aggregate subnets

[coffeegist]

Describe the bug
I expect, if I filter input using the -fi command, and then aggregate with -a to the minimum number of subnets, that the subnets generated would match the output given if -a is not provided. However, the filtered IPs are added back in after aggregating. Is there another way to exclude IPs and aggregate them back to the minimal subnets that do not include the filtered addresses?

Mapcidr version
Include the version of mapcidr you are using, mapcidr -version

$ mapcidr --version

$ mapcidr -silent -cl 10.0.0.0/30

I suppose a workaround would be the following

$ mapcidr -silent -cl 10.0.0.0/30 -fi 10.0.0.1 | mapcidr -silent -a
10.0.0.0/32
10.0.0.2/31
