Function IsNetworkPort

IsNetworkPort(options?): PropertyDecorator
Checks if the given value is a valid port number.

This is similar to the built-in @IsPort except that it requires the value to be a number (not a string).

Example
```
// Ensure the value is a valid network port (but not 0).
@IsNetworkPort({ allow_system_allocated: false })
remotePort: number
```
Parameters
- Optional options: {
  allow_system_allocated?: boolean;
  allow_system_ports?: boolean;
  } & ValidationOptions
  Accepts the following options (in addition to generic class-validator options):
  - allow_system_allocated: boolean = true If true, allow port 0 (system allocated).
  - allow_system_ports: boolean = true If true, allow ports below 1024.
