eac0df1379 musig: mention how keyagg_cache tweak and parity relate to spec 
Also rename internal_key_parity -> parity_acc because the former is

57eb6b4167 musig-spec: move description of secret key negation to spec 
Also fix bug in description that resulted in a wrong definition of t.
And rename keyagg coefficient from 'mu' to 'a' since we don't use the term "musig
coefficient" anymore and a is what is used in the paper.
