fix(hip): from_data raises AttributeError, alias reads _info before it is set #1184

Describe the bug
HIP.from_data(info) raises AttributeError: 'HIP' object has no attribute '_info'. The alias property (pcapkit/protocols/internet/hip.py:475) reads self._info.version before _info is set, and _decode_next_layer (internet.py:236) reaches it during the rebuild.

To Reproduce
Parse frame #99 of options-internet.pcap, take its HIP layer's info, and call HIP.from_data on it. This reproduces on origin/main (20438e3ec).

Impact
Once #1182 lands, IPv6.from_data rebuilds the extension chain by calling each header's from_data. The 48–49 IPv6>HIP capture frames then raise this error instead of returning wrong bytes.

Found by the #1182 worker. The #1182 cross-review reproduced it independently.
