[RoN] [2-6] Quicksand RI

There's some visual changes, balance and fixes.

Global:

• Rich spots has been changed. Now they has ancient debris instead of standard diamond ore. (10 diamond & emerald -> 9 ancient debris).
• All hyphae blocks was changed to acacia wood. (p.s. nether wood provide 2 more wood, so it's was unfair).
• Player start positions now more friendly to the piglins race.
• All ore clusters now has more accessibilities by workers (should stupidly jump less).

By region:

Castle.

• Now it's convertable to nether biome.
• No more buildings could be placed on the wall (I hope so).

Nether.

• Now it's less friendly for piglins & visual changes.

Desert.

• Should be more friendly for building placement.

Red sand deserts & crimson has no significant changes.
