Dasha algorithm: consider only rules where target increases

[Zmicier Zaleznicenka]

Implement a switch. If it is turned off, analysis should consider all the rules. If it is turned on, analysis should only consider rules where baseline < target. This is needed not to report the cases when target performance improves in comparison with baseline.

[Zmicier Zaleznicenka]

Plus per-counter option showing the direction, either consider violation only if target > baseline, or if target < baseline.

[Zmicier Zaleznicenka]

Also somehow treat violations as more important if the most confident categories are significantly far from each other.
