Request for RefactoringMiner API to detect between directories

[ketkarameya]

@tsantalis I was wondering if you plan on (or open to ) add another RMiner API (like detectAtCommit we could have detectBetweenDirectories) that mines Refactorings between 2 versions of a project stored in separate directories. I can contribute this, if this is something you are okay to add to RMiner.

The functionality is already there https://github.com/tsantalis/RefactoringMiner#with-two-directories-containing-java-source-code We just need an API for it. Go ahead with the feature and I will merge it.
