sniffers can be ignore/pathfinding some Dangerous blocks (Such as wither rose, dripstones & powder snow) just like MC-260777

Step to reproduce

wither rose

1. Create a wither rose ring setup
2. spawn sniffer to center

powder snow

1. create 2 side of square powder snow ring
2. spawn sniffer to center

dripstone

1. create tower with 3x5x3 blocks
2. create single block of dripstone over the bottom of ring
3. spawn sniffer to top of center in tower

final step

Waiting while sniffing or walking

Observed results

The sniffer can be pathfind/ignore Dangerous blocks 

Expected Behaviour

Sniffer can should not be pathfind/ignore Dangerous blocks 

Note

This sniffers did not pathfind in lava, magma block and campfires that work as safe
