New Ganonhunt goal

[tcprescott]

Adds a new goal called "Ganonhunt". There are some things that I think we may still need to do regarding this PR, but I wanted to give you at least a first look at it. This will not currently work with Entrance Randomizer, and as a result it has been explicitly disabled. The frontend will force entrance shuffle off if the new goal is chosen, and if entrances are turned on while the new goal is chosen, it'll set the goal to Fast Ganon.

Rules:

1. Pyramid is pre-opened.
2. Agahnim 2 is not required
3. Crystals are not required to defeat Ganon. Ganon vulnerability is strictly 40 Triforce Pieces.
4. Crystals are still required for GT entry. GT fill rules are the same as the other Ganon goals.

Remaining (potential) tasks:

• Get i18n from the community. Right now there's just placeholder English in place for the goal name and description.
• Unit tests: Are unit tests needed for this?
• Bug testing
• Potentially update ER to also support this goal.
• Right now it places 60 pieces, and 40 are required to engage Ganon. This may require further tuning discussion.

overall looks good to me, I figured we could update the ganon settings in Rom.php to match what is available in base rom
