Whole structure block detection

[KingofAnomaly]

Is your feature request related to a problem? Please describe.
Structures keep cutting into trees making the generation look unnatural.

Describe the solution you'd like
A whitelist and blacklist of blocks the structure can destroy when it spawns. This would allow people to blacklist leaves or logs so their structures don't spawn partly inside of a tree.

Describe alternatives you've considered
I have tried making the area for the structure bigger to cut out any trees nearby but it still has the same issues. I have also tried using the block level limit but it doesn't seem to detect trees unless it is set to be very flat which the structure itself doesn't need super flat land.

Additional context
Here are some images of boulders I have made to spawn around the world but they dont' do well in forests

Trees are are ignored by structure generation, including things like the blocklevellimit. You could try using the block_replacement feature to replace logs and leaves with air.

[KingofAnomaly]

I have not tried block_replacement yet but I have thought about it my only concern is that it would still leave pieces of tree just outside of the structure's area

[KingofAnomaly]

I also have an issue where blocks are spawning in trees even though only grass, stone and dirt blocks are on the spawn blocks whitelist.

maybe a setting to ignore trees that is separate from the ignore plants option might be useful
