camelCase vs snake_case inconsistency

node-telegram-bot-api uses snake_case where the Telegram API does, for consistency with the API. In coffea, some places (evt.raw and options in the object passed to reply()) use snake_case, while others use camelCase.

camelCase is the de facto standard for JavaScript code, however, I think it's more important to stay close to the API in places where the raw interface is exposed, which mostly includes reply() too. eslint can be configured to ignore non-compliance in these places with ["camelcase", {"properties": "never"}] (which is used by standard).

Either way, the current state is horribly inconsistent, so either snake_case should be consistently used where the Telegram API uses it, or camelCase should be used consistently across the whole library.
