[1.15.X Fabric] Seed Cracker v0.1.0-beta

Huge release with tons of features, bug fixes and performance improvements. Please report any bugs you find as this is probably the last release before 1.16.

• New commands-- /seed cracker <ON/OFF>, /seed data clear and /seed data bits.
• Performance improvements with finders looking for features within chunks.
• Near quadrupled brute-forcing speed by reorganizing the feature list.
• Added support for end and nether biomes.
• Added progress updates when looking for seeds.
• All seeds are now highlighted and can be copied with one click.
• Added dungeon floor finder.

In this release, dungeons have been turned off by default (you can re-enable them with /seed finder type DUNGEON ON) because of a new experimental feature that was implemented (see #12). With it enabled, it becomes possible to crack the seed without the end dimension.
