Allow case insensitive deserialization of String value into boolean/Boolean (esp for Excel) #1852
Description
At the moment, com.fasterxml.jackson.databind.deser.std.NumberDeserializers.BooleanDeserializer#_parseBoolean support only "true" and "True" (and the same for false) but fails for values like "TRUE" It would be great to do the matching case insensitive out of the box (similar to how java.lang.Boolean#parseBoolean checks for true)
