No explicit way to map between io_group and TPC #313
Description
The maps provided by detector.py seem to reflect an older pattern where each io_group represents a whole anode, which is no longer true for FSD-scale modules. This leaves some ambiguity in the mapping between the io_group ID and the TPC index when there is more than one io_group per anode.
What is provided:
MODULE_TO_IO_GROUPS: This dictionary allows for lookup of the module ID given a packet's io_group field.
MODULE_TO_TPCS: This dictionary allows for lookup of a module given the TPC is known. It also allows one to inspect which TPCs belong to each module.
What is desired:
TPC_TO_IO_GROUPS or IO_GROUP_TO_TPCS: An explicit mapping between io_group and TPC ID. If there is a known way to do this, it is not made clear in the documentation or examples, and an explicit way to make this translation should be provided by detector.py.
