Ban Map types in JSON related functions.

[samchon]

In the below reason, typia banned Map types on the JSON related functions.

Following the policy of typia, nestia also bans such unsupported types on the JSON related functions.

When JSON.stringify() function be called about Map<Key, T> type, it always returns the empty bracket value {}. Until now, I'd developed typia to return the empty bracket value {}, following the standard JSON.stringify() function.

However, as most TypeScript/JavaScript developers do not know about that and there's not any problem when using the Map type on typia.json.stringify<T>() function ini the compile time, it was possible to misunderstand that typia's stringify function has a bug about the Map time.

In such reason, I've decided to throw a compile error when such non-supported type being used in the typia.json functions. Also, such strategy would be helpful for typia users to avoid taking a mistake using such non-supported type on the JSON functions.
