add option to raise counts to power before exact negative sampling
fix bug using Int.MaxValue instead of Long.MaxValue when processing wikipedia, since we were capping at 2.14bb contexts, indicating we were running into the limit before finishing wikipedia. also remove default arguments for wiki pages since they are extremely bug prone and always overridden (and there were multiple bugs in this area that we fixed before)
