[Feature request] Add resetUserId to API

[svdo]

Hi,

Thanks for providing this module, it is rather convenient. The official Matomo API is of course richer than this wrapper, that's OK. There is one function specifically that I miss however: resetUserId. Would you be interested in adding this so that we can also handle situations where a user logs out? See also: https://developer.matomo.org/guides/tracking-javascript-guide#when-user-logs-out-reset-user-id.

Thank you!

@svdo thanks for feedback.
