added :excludeRange and :includeRange methods to DynBPFFilter class

Short description

Wanting to move from DynBlockRulesGroup to DynBPFFilter, I found the excludeRange and includeRange methods missing, while the rest of the functionality between both ways of dynamically blocking was rather identical. So, I added them.
