Typo in Arduino/tools/elf2bin.py gives key error when using qout flash mode.

[micjoc]

Just upgraded to 2.2.1. Generating the bin file did not work in one design because it was using qout mode. Could nail it down to this typo 'quot' instead of 'qout' gives a dictionary error when running it.

Arduino/tools/elf2bin.py
Line 22: fmodeb = { 'dout': 3, 'dio': 2, 'quot': 1, 'qio': 0 }

should be:
fmodeb = { 'dout': 3, 'dio': 2, 'qout': 1, 'qio': 0 }
