feat: add coords to acquisition return data

Explanation of changes

This MR adds the coords to the return data.

Additionally, one small change I added to the generate_acq_channels_data is that the

• loop_repetition and acq_index_legacy keys in the "coords" are slightly changed to loop_repetition_{acq_channel} and acq_index_legacy_{acq_channel},
• and removed loop_repetition from operations which are outside of loops.

See &5 (closed).
