Compare results between two Robocop runs

[bhirsz]

It would be good to have some way of comparing two Robocop runs ie number of new/fixed issues. It could be special report (--report compare).

Other cli tools usually create special directory (like .pylint or .coverage) and store run results there - which is accessed in 2nd and evaluated in 2nd run.

If we rely on external tools, we can use SARIF results with the sarif tool:

dir>sarif diff .sarif.json .sarif2.json
error level: +0 -0 no changes
warning level: +0 +0
  Number of occurrences 35 -> 34 (-1) for issue "0702 Missing blank space after comment character"
note level: +0 -0 no changes
all levels: +0 +0
