Description

Even though Boolean to String/Char/Varchar conversion needs special handling (explicitly converting 1s to 'TRUE's and 0s to 'FALSE's) we are currently using the same logic for all numeric vectors (StringGroupFromAnyIntegerTreeReader).

StringGroupFromBooleanTreeReader logic is there but seems broken since ORC-531 refactor.
