make [Flags] enumeration serialization PrettyPrint aware
stopgap commit; hash-based approach to parsing enumerations when possible, is case-sensitive at the moment which makes it unshippable
make hash-based enum parsing case-insensitive; the tolower isn't ideal here just yet though
speed up ToLowerChar; this is just for reference, because it's not baked in that switch can't stick around
remove this switch going forward
