how much memory is used per item / false positive percentage?

1. lower false positive rates = higher memory used. is there a vague guide on the number of bytes?

    filter := bloom.NewWithEstimates(1000000, 0.01) 

2. for a cdn deployment with 100 million items, what's a good number for the bloom item count and false positive rate? also how much memory is needed for this bloom filter?

3. i was thinking if it's using a lot of memory, would it be advisable to use roaring bitmaps as "replacement" to bloom filter as suggested by chatgpt here: https://github.com/RoaringBitmap/roaring/issues/388
