add hybrid fastcs/adodin eiger. moved from ophyd_async branch

[RJCD-Diamond]

After discussions with @coretl and given the fact that we will be removing the adodin in order to only support fascs odin, the adodin module has been moved to dls-dodal in order to maintain compatibility until all EIger's have been moved to fascs odin

Thanks, I think this is mostly fine my only comments would be:

• Should: We should remove the one in ophyd_async now. I think that this is the only place it's used in DLS and I don't think it's yet used anywhere else. Otherwise having the two is confusing
• Nit: I don't think the ad in the path or filename adds anything as we don't have one that's not AD yet and once we do we should prioritise moving to that so hopefully this isn't around for long. e.g. I would just call it src/dodal/devices/async_eiger/odin_io.py

Nit: Why were these added?

Also, FYI @jacob720, can you take a look at this as you've been working on it too?
