[Suggestion] Support tag tables in loki loging

[sw4m]

Is your feature request related to a problem? Please describe.
When configured for loki, lib.logger does not support tables in the additional arguments.. So all the tags have to be set in a k:v string and that is really frustrating, since other methods do support tables.

Describe the solution you'd like
I am already working on a pull request to add support for having a table with tags as an argument.

#75 Mentions that loki supports tables already, but it is not true, since when a table is passed into string.tostringall, lua returns the table reference for some reason.
