Upgrade +9

## 0.37.0

### Balance
- Success chances increased across all materials, so reaching +9 is much more accessible.
  - Diamond / Netherite: 100, 95, 90, 85, 75, 65, 55, 45, 35 %
  - Iron: 100, 100, 95, 90, 85, 75, 65, 55, 45 %
  - Wood / Leather / Stone / Gold: 100, 100, 100, 95, 90, 85, 75, 65, 55 %
- All 63 recipes reworked: simpler ingredients, at most 4 per recipe, and Diamond = Netherite and Wood = Leather = Stone = Gold now share the same recipe.
- Failure penalties are unchanged (+1 to +3: none, +4 to +6: −1 level, +7 to +8: −2, +9: −3). A Totem of Undying still prevents the level loss.

### New
- Pickaxes, shovels and hoes (wood, stone, gold, iron, diamond, netherite) can now be upgraded. Axes already could. Upgraded tools mine faster: up to +50 % at +9 (+55 % diamond, +65 % netherite) on the blocks they are meant for. It stacks with Efficiency and Haste.
- Recipe config: edit success chance, level loss and ingredients per recipe in config/upgrade_plus_9-recipes.json (items from other mods are supported). Applied on restart or /reload.
- French translation added (English and Spanish reviewed).
- New mod logo.

### Changed
- New design for the Fusion Table: flat base, wooden pillar and a grey stone top, without the green colour and the partial steps at the bottom.

### Notes
- Equipment is never destroyed on a failed fusion. If the mod is removed, upgraded gear simply keeps working as normal vanilla gear.
