Implement 2 layer coincidence detection model

[kaolpr]

• Convert current trigger controller into general coincidence detection block. Keep input trigger registration mechanism. Every module will have a single output and will be represented as a single RTIO channel.

Create a new trigger controller that will:

• Instantiate coincidence blocks for every scintilator

• Combine their outputs and pass as inputs to a configurable number (not less than number of scitilators) of 2nd layer coincidence blocks.

• Add software trigger for every output channel.

• Crete coredevice for general coincidence detection block.

• Update trigger controller coredevice to reflect changes.

• Create documentation for triggering subsystem.
