187: Added cascaded IIR with server commands for up to 2 cascaded IIRs per… r=jordens a=nkuh

… channel.

Note: If the number of cascaded IIRs is set to 1 the still existent server commands for the unused 2nd cascade level will be aliases for the 1st level.

180: Feature/adc dac io macros r=jordens a=jordens

I wanted to try macros.
This moves the ADC and DAC DMA setup into macros reducing code footprint. Hopefully no functional changes there.
I didn't test this on hardware and I may have missed differences between `Adc0`/`Adc1` and `Dac0`/`Dac1`.

It removes the `AdcInputs` and `DacOutputs` structs and replaces them with tuples as they were just fan-outs/fan-ins.
It also does some minor tweaks in the `process()` ISR towards higher flexibility enforces some data patterns to help the compiler.

Differences missing:
* [x] `.transfer_complete_interrupt(true)` for `Adc1` only: needed
* [x] `.circular_buffer(true);` for `Dac1` only: close #183
