Fix: change output to the agreed format

[sillitoe]

Output should now match the agreed format for domain prediction

chain_id   sequence_md5   nres   ndom   chopping   uncertainty

Overview of changes:

• results are now one line per chain (not one line per segment)
• results include extra cols: md5, nres, ndom
• remove function
• updated tests

@JudeWells - before merging, can you please check that the new output format still makes sense, especially for discontinuous domains

The expected results for end-to-end tests have changed from:

chain_id    domain_id   chopping    uncertainty
AF-A0A1W2PQ64-F1-model_v4   domain_1    6-39    0.0444
AF-A0A1W2PQ64-F1-model_v4   domain_1    94-192  0.0444
AF-A0A1W2PQ64-F1-model_v4   domain_2    41-90   0.0444

to:

chain_id  sequence_md5   nres   ndom   chopping   uncertainty
AF-A0A1W2PQ64-F1-model_v4   a126e3d4d1a2dcadaa684287855d19f4   194   2   6-39_94-192,41-90  0.0444
