v1.9.1 to fix bug of wrong reqStates

### Release v1.9.1

1. Fix bug of wrong `reqStates`. Check [Release 1.9 breakes previously running code #39](khoih-prog/AsyncHTTPRequest_Generic#39) and [Callback behaviour is buggy (ESP8266) #43](khoih-prog/AsyncHTTPRequest_Generic#43).
2. Optional larger `DEFAULT_RX_TIMEOUT` from default 3s, for slower networks
