Replace assert() by Error_Handler()

Avoid to include "assert.h" which relies on printf().
This allow to save space:
Example for CardInfo.ino sketche for the same target:
- with assert:
  Sketch uses 35308 bytes (6%) of program storage space. Maximum is 524288 bytes.
  Global variables use 2384 bytes (1%) of dynamic memory, leaving 128688 bytes for local variables. Maximum is 131072 bytes.
- without assert:
  Sketch uses 31844 bytes (6%) of program storage space. Maximum is 524288 bytes.
  Global variables use 2284 bytes (1%) of dynamic memory, leaving 128788 bytes for local variables. Maximum is 131072 bytes.
