Sculk Tendrils and Sculk Snares

The current experimental snapshot added Deep Dark biomes but it felt lack luster compared to Lush Caves and Dripstone Caves. So I would like to add Sculk Tendrils and Sculk Snares.

Sculk Snares act like vines that reach up. You can climb on these but staying on these for too long traps you, preventing you from escaping. It then proceeds to pull you down, and keep you from moving for a set duration.
Sculk Tendrils are similar to Sculk Snares but it hangs down. The difference is staying on these for too long makes you loose your grip to the Tendrils and apply heavy slowness.

Both of these alert the nearby Sculk Sensors and Sculk Shriekers.
