SCMLogParser Handle Reverts

Nobody has claimed this yet.

# Feature request
Add an option to handle reverted commits.

## Description

As a user I want the option to controll if reverted commits should be included in the calculation or not.
If they are not included I expect the parser to correctly substract reverted metrics as well, removing the previosly calculated commit.

## Acceptance criteria
- the parser supports a new flag to toggle revert commit handling, which is false per default
- setting the flag to true will result in the parser watching for reverted commits and not including them in the final calculation
- in case of reverted commits the previously calculated metrics for the commit are also correctly substracted
- the parser needs to only recognize reverts by the 'Revert someHashVlaue' construct in commit title

## Assumptions & Exclusions
- exclusion: custom revert messages are not considered, maybe in a further PR

## Development notes (optional Task Breakdown)
- [ ] add flag for toggeling revert commit modemode
- [ ] 'Revert someHashVlaue' construct in commit title
- [ ] adjust reverted metrics accordingly

Start by locating SCMLogParser and its existing commit-metric calculation. Trace how commit titles are parsed, then use the acceptance criteria to verify the default-off flag, exact “Revert someHashVlaue” recognition, exclusion from the final calculation, and subtraction of the reverted commit’s metrics.
