v2022.11

• For kilonovae, enable seeding with initial energy in the q column of
  model.txt
• Add kilonova test calculation to GitHub actions (to test alpha/beta
  decays and thermalisation)
• exspec: read all packets files into memory if total size is below a
  limit (maxpktmem_mb = 6000). This makes angle-resolved files much faster
  to generate.
• Prepend each log line with the date and time
• Fix escaping direction bin for non-normalised direction vectors
• Reduce memory fragmentation by making block allocation for atomic
  transition arrays and sharing on node
• Use C++ std library search functions (faster and less code)

A 1D Sim+2010 Sub-MCh test with classic options gives about an 8-11%
decrease in run time.
