This PR adds the following background functions:

  • hubble_distance(cosmo, a)
  • comoving_volume_element(cosmo, a)
  • comoving_volume(cosmo, a, *, solid_angle=4*pi)
  • lookback_time(cosmo, a)
  • age_of_universe(cosmo, a)

and with that closes #954 and closes #408 and now CCL will be able to calculate every distance quantity described in Hogg's reference manual .

This is not to be reviewed until current functionality has been put in v3 form. There are several other new science implementations that take priority.
