object_hata OK

[EllipticEllipsis]

N.B. This object crashes the current version of z64utils due to faulty detection of the collision at the beginning. I hear that @Thar0 has implemented a fix, but it's not in yet.

Debinarised object_hata completely, added symbols to EnHata, made an enum for limbs, renamed a couple of things.

Unfortunately, the way the limbs are used in code implied it was necessary to make an enum, but the structure of the skeleton in this one made the limbs annoying to name: essentially it has the shape

where * means a dList is attatched. Each flag is formed from nodes where the first child is the next position, the second has the other limb, not displaced, with the dList attached. (This structure may be typical of non-flex skeletons, I'm not sure.) I went with naming the limbs with dLists after the dList, and the corresponding parent with the suffix Base; I'm open to better alternatives.

Also noticed that the unused data bore a striking resemblence to a ColliderCylinderInit and CollisionCheckInfoInit2, Combined with the suspicious 0x4C-sized gap in the struct, I took it as sufficient evidence to format it as a ColliderInit and write the gap as a collider, with a note to say it's unused.

Finally, fixed a couple of compiler warnings in EnRiverSound.

Looks nice and clean.
