v0.7.4

This is a patch release from v0.7.3 → v0.7.4.

Fixes

• Skip callbacks with dead weakrefs while iterating over callbacks in pyhf events, like pyhf.set_backend, to avoid the possibility of accessing dead weakrefs before they could be garbage collected. (PR #2310)

  The fixed bug was subtle and occurred nondeterministically when the pyhf.tensorlib was changed repeatedly causing dead weakrefs to be accessed before Python's garbage collection could remove them. Most users should be unaffected.
