Add ability to declare IPAddress when configuring a Port

[05nelsonm]

See #312 (comment)

Would be preferred to have some sort of Localhost object where resolution of the actual loopback IP address can be had.

The configuration should accept IPaddress?

Need to also verify how not including a prefixing IP address will be handled by tor. Documentation states that 127.0.0.1 will be used, which is entirely incorrect.

I think this functionality is great, but maybe not necessary until after a 2.0.0-alpha01 release.

I see it as being able to pass in LocalHost.IPv4 or LocalHost.IPv6, as well as maybe another Address type of AnyHost

public sealed class AnyHost private constructor(
    @JvmField
    public val address: IPAddress,
): Address(address.value) {

    public object IPv4: AnyHost("0.0.0.0".toIPAddressV4())
    public object IPv6: AnyHost("::0".toIPAddressV6())
}

May also want to consider adding the TorConfig settings for IP protocol preferences.

Will do this in future 2.x.0 release
