Closes #224
The problem described in the issue above is caused by an incompatibility between the vocabulary provided by the user and the regex used to create the DFA. This issue is typically caused by a wrongful encoding of the the vocabulary by the user (special tokens from their tokenizer are included).
This PR proposes to do 2 things about it:
Indexobject to raise an error at initialization if such an incompatibility exist (instead of leading to a situation in which an error could arise during inference)Vocabularyand warn users about this problem
