Add tautomer rule-based index support for bingo

**Background**
For new approach with tautomer rules update existing indexing to be able

**Solution**
* Add new parameter into createDatabaseFile() "TAU-RULES" (change name ...)
* If parameter is used, then additional section with tautomers (transformed additional molecules) should be created inside index according to the rules (location of rule TBD)
* while search, searchSub() if "TAU" specified, then it should use the "TAU-RULES" algorithm
