Expand unit tests (#130)

This is an initial set of tests to cover some of the peripherals. It will be expanded on in the future.

* Add basic CRC test

* add tests for common EXTI

* add iwdg test cases

* Add partial OTP coverage
Expand machines for tests

* Add qtest pulse check function

* - Fix some bugs in G070 exti
- Add test coverage for exti

* Add test case for g070 flash controller

* - Add machines for f4xx
- Add clock flags to RNG
- Add RNG test

* Adapt previous FINT cases for F4xx

* add test case for RCC peripheral resets.

* Add ADC test case for common ADC

* Add ADCC coverage, fix prescale calculation.

* - Fix bugs in ADC align and resolution
- Add test cases for align, DMAR

* - Add tests for DMA unit
- Fix stride/data copies for mismatched sizes
- fix circular mode in both directions

* - Add partial uart test case (baud rate broken)
- Change some macros to functions for better coverage reporting

* - fix F4xx dma implementation issues
- Add test cases for F4xx dma

* add DBG test case

* Fix DMA bugs
