Encoders demo: fixed bug; bumped version to 1.0.3

Since the first call to checkErrorLeft() and checkErrorRight() would
have already cleared the encoder error flags, calling those functions
again right away meant errors would never be reported on the display
unless an error occurred between the two calls.

 ## Version history
 
+* 1.0.3 (2022-09-06): Fixed a bug in the Encoders demo that could prevent encoder errors from being shown properly on the display.
 * 1.0.2 (2017-07-17): Fixed a bug that caused errors for the right encoder to be reported as errors for the left encoder.
 * 1.0.1 (2017-02-23):
   * Changed the internal `Romi32U4Motors::maxSpeed` variable to be an `int16_t` so it can be compared to other `int16_t` variables without warnings.
