feat(layer): simple renames of flattened event fields

[mladedav]

Motivation

Closes #19.

Users sometimes want to rename the fields in events and spans. This allows that specifically for flattened events. This should be done more generally somehow.

Solution

Accept a closure and a state object, calling the closure for every field to assess whether to rename or not. This will most likely be a lookup in a map.
