Btrfs: heuristic: add byte core set calculation
Calculate byte core set for data sample:
- sort buckets' numbers in decreasing order
- count how many values cover 90% of the sample
If the core set size is low (<=25%), data are easily compressible.
If the core set size is high (>=80%), data are not compressible.
