Describe the bug

Some range registered ports are returned incorrectly

To Reproduce

make build
./httpref ports 16404
16384-16403
[... redacted ...]

Expected behavior

The range returned should include the port requested. Like so:

./httpref ports 16404
16403-16472
[... redacted ...]

Desktop

System Version: macOS 10.15.5 (19F101) Kernel Version: Darwin 19.5.0

Additional context

The httpref.InRange function should change a condition from if code >= parts[0] || code <= parts[len(parts)-1] to if code >= parts[0] && code <= parts[len(parts)-1] to correctly identify the range.

I would like to submit a PR fixing this issue and improving the test case to ensure that the expected range is returned. Is that okay with you?
