feature - extend api

extend engine to support features from Jurebes

# fuzzy matching
engine.enable_fuzzy()
engine.disable_fuzzy()

# temporarily disable a intent
engine.detach_intent("name")
engine.reatach_intent("name")

# force correct predictions
engine.exclude_keywords("name", ["laugh"])
engine.exclude_keywords("hello", ["laugh"])
print(engine.calc_intent("make me laugh"))
# IntentMatch(intent_name='joke', confidence=1.0, entities={})

# inject context
engine.set_context("joke", "joke_type", "chuck_norris")  # if a value is passed it will populate entities
print(engine.calc_intent("tell me a chuch norris joke")) 
# IntentMatch(intent_name='joke', confidence=0.9707841337857908, entities={'joke_type': 'chuck_norris'})

# require context
engine.require_context("joke", "joke_type")
engine.unrequire_context("joke", "joke_type")

# exclude intent matches based on context
engine.exclude_context("hello", "said_hello")
engine.set_context("hello", "said_hello")  # now wont predict hello intent

Start by comparing the listed Jurebes advanced-usage features with padacioso's existing engine API, focusing on fuzzy matching, intent attachment, keyword exclusion, and context handling. The issue names no files or tests; done would mean the requested engine operations are supported and produce the shown intent results.
