DS2: Adding support for traps

Goes with this PR for the DS2 client

Traps, Death Link, Shared Traps (DS2 -> DS2 only), Random Carvings on (death or trap)

• Adds a preset trap option (can be overridden manually, must know keys which is not great atm)
• This also fixed a minor inconvenience with how the the ItemData class manipulated the item_type field. Remove the post_init function after writing all of the item_data to a file and pulling the item_type values into the source code (items.py)
• Includes mapping functions for trap name and option name
• currently tested playing through an async archipelago with all new settings enabled (max traps)
• tested with 2 DS2 games running, sending traps via pickup and shop just fine -- local, and hosted (both vanilla and sotfs)
