v1.6.1 to not destroy original CString

#### Releases v1.6.1

1. Don't need `memmove()`, CString no longer destroyed. Check [All memmove() removed - string no longer destroyed #11](khoih-prog/Portenta_H7_AsyncWebServer#11)

 ### Important Note from v1.6.0
 
-The new `v1.6.0+` has added a new and powerful feature to permit using `CString` in optional `SDRAM` to save heap to send `very large data`.
