[Feature] Support for Nmap-style IP Range Syntax

[m101]

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

Please consider adding support for Nmap-style IP range input syntax in mapcidr.

This includes formats like:

• Dash ranges (e.g., 192.168.1.1-10)
• Ranges in any octet (e.g., 192.168.0-3.5-10)
• Comma-separated targets (e.g., 192.168.1.1,192.168.1.5-10)

Describe the solution you'd like

Extend mapcidr to accept and expand the following syntaxes:

• Dash-based ranges:

echo "192.168.1.1-5" |  mapcidr
  # → 192.168.1.1, 192.168.1.2, ..., 192.168.1.5

• Multi-octet ranges:

echo "192.168.0-1.1-2" | mapcidr
# → 192.168.0.1, 192.168.0.2, 192.168.1.1, 192.168.1.2

• Comma-separated values:

mapcidr -range "10.0.0.1,10.0.0.5-7,10.0.1.0/30"
# → 10.0.0.1, 10.0.0.5, 10.0.0.6, 10.0.0.5, 10.0.1.0, 10.0.1.1, 10.0.1.2, 10.0.1.3

This would mirror Nmap’s flexible input parsing while keeping the output behavior of mapcidr.
