Add bytes function to IPAddress

[05nelsonm]

• Add ByteArray.toIPAddress
• Add ByteArray.toIPAddressOrNull
• Add ByteArray.toIPAddressV4
• Add ByteArray.toIPAddressV4OrNull
• Add ByteArray.toIPAddressV6
• Add ByteArray.toIPAddressV6OrNull

Within the IPAddress sealed class a bytes() function should be available which would produce a copy of the private field ByteArray.

This will also allow for expansion of the IPv6 addresses in order to produce uniformity such that the Address.value is always the same. Might even want to lift the final override for equals & hashCode such that IPAddress implementation can compare the underlying byte field.

Also will be able to add Jvm extension functions for toInetAddress using InetAddress.getByAddress

Will do this in future 2.x.0 release

Edit: needed for implementing TorCmd.MapAddress
