* Refactor: separate out schedule calcs from speeduino.ino
(so they can be unit tested)
* Add unit tests for compute_delay
* Use PROGMEM to store test input & output
* Add some 720 unit tests
* Rename unit test file
* Test ignition codepaths 2-8
* Test ign1 calcs
* Add first injector calc tests
* Add 720 deg tests
Simplify
* Simplify test_calc_inj1_timeout
* Claw back RAM
* Simplify test framework
Channel angle is part of the test data set.
* Move schedule calculation unit tests into their own harness
Competing for RAM with the rest of Speeduino
can cause them to fail,
* Performance: inline all schedule calcs.
* Unit test end angle
* Unit test calculateIgnitionAngle1
* Test start angles also
And test end angles for channel 1
* Unit test calculateIgnitionAngle3
* Unit test calculateIgnitionAngle4
* Improve unit test output
* Add Nissan360 decoder unit tests.
* Add Ford ST170 decoder unit tests
* Add NGC decoder unit tests
