Before this change jansi was used by the compiler,
unless "kotlin.colors.enabled" is not set to false.
This caused multiple issues in different build systems,
where newer or older version of jansi could crash the JVM
since it uses native code.
The following short term solutions were discussed:
* Set "kotlin.colors.enabled" to false where jansi is not needed
(basically in any build system).
* Set "kotlin.colors.enabled" to true where jansi is needed,
and use it only when the system property is set to true.
Escaped codes are only needed in CLI tools (kotlinc, REPL),
so the second solution is preferred (less places to set the property).
