fix: pass skipSpecialTokens param to Tokenizer in _TokenizerModule (#175)

## Description

Currently, the native module accepts two params, namely tokens to decode
and a flag whether we should skip special tokens. The _TokenizerModule
wrapper's decode called Tokenizer.decode with just the tokens to decode
param, resulting in wrong parameters being passed to native side. This
PR solves that problem.
