Allow multistep recipes in Java Edition and make the Bedrock Edition search more advanced.

This also improves the algorithm for finding a recipe for a given target color (the one used in /src/tools/armorColor/worker.ts).

Problem: I don't know exactly what the UI should look like.

All of these notes relate to functions in /src/utils/color/index.ts.

Okay, so some notes. search_je has a few magic numbers:

• mix_u.dyemax_limit = 8;
• mix_u.dyec_limit = 16;
• mix_u.craftc_limit = 4;
  This means search for recipes in Java Edition using 1 to 8 dyes per craft, up to 16 dyes total, and up to 4 crafts total.

Also, search_be_filler is optional. So you could remove the call to it in search_be. It simply adds more Bedrock Edition recipes.

• There is a variable called splits which determines how many recipes are checked per color in search_be_filler. Making the numbers in splits smaller will make it take less time. And making them bigger will make it take more time but discover more recipes.

Finally, in class MixU_BE, there is this line:

• max_dyes: number = 6;
  This tells the server to do a search for all 1 to 6 dye recipes in Bedrock Edition. This could probably be expanded to 7 or 8. 7 literally takes 16 times as long to search, and 8 literally takes 256 times as long.
