Add support for ELS Boost V2 (#19)

* Fix 8-bit SPI mode for EEPROM.

* Add support for V2 EEPROM.

* Add test fixture project.

* Build test fixture

* Test key inputs and drive Larson scanner.

* Add 8K EEPROM testing.

* Fix comment.

* VREG test working on A5

* VREG test now working on Analog in B1.

* Finish test fixture.

Add stepper and alarm pin tests
Allow EEPROMs larger than 8K
Loosen VREG constraint to allow for unreliable pogo resistance

* Simplified test code.

* Fix VREG test.

* Switch default configuration to hardware version 2.

* Roll version number to 1.1.00
