chore: add -compat suffix to v1 tests
format and rewrite code comments
use a setter for traceurOverrides so that a deprecated message can be printed
use private instance of traceurOverrides property instead of exported since there is no getter and add getter for backward compat
add deprecation messages to v1 exported properties
move es6ifyConfigure method to bottom of file so that it is together with the deprecated properties
rename option to traceurOverrides
add transform test file
use console.warn for deprecation messages
rename test bundle directory
add errors test which is the same as the compat since the new api supports the pure transform function
