What does this pull request do?

Fishing will need to be converted to lua at some point or another, for all unimplemented stuff, so I thought we may just start now.

• Adds fish enums to item.lua
• Adds/renames fish duplicates and adjusts the enum name when/where used.
• Converts the 3 main fishing data table to lua, to be used on a future logic rewrite. It was a massive and boring job, but added some TODOs already regarding the data in them.

Steps to test these changes

Nothing to test.
