[Fisherman] Idea for fisherman perk(s)

[rainbowcraft2]

Here's my idea:
Starting at level 10, fisherman should start getting access to unique fishing rewards.
At 10 they get access to tier 1 catches
At 25 they get access tier 2 catches
At 40 they get access to tier 3 catches

Tier 1 (5% of catches are a tier 1 special catch)
Things like monster essence, umami, diamonds, emeralds, and enchanted books with tier 1 custom enchantments (tiers based on ensorcel tiers)

Tier 2 (1.25% of catches are a tier 2 special catch)
Things like wither skeleton shards, treasure map fragments, and enchanted books with tier 2 custom enchants

Tier 3 (0.25% of catches are a tier 3 special catch)
Things like flawless/pure items and heroic monster essence
