Subject: [PATCH] [mod] Remove support for long-deprecated `:?err_`, `:vargs_`
 delays in log data

Relevant only to folks with custom appenders and/or middleware.

This commit removes the `:?err_` and `:vargs_` keys from Timbre's log data map.
Instead, just use `:?err` and `:vargs`.

See the `*config*` docstring for more info on Timbre's log data map.
