toasty 0.18.0

toasty 0.18.0 (2022-09-06)

This release of Toasty contains a whole boatload of improvements! There are
no less than three major ones:

• Support tiling FITS data to the all-sky TOAST projection (#86, @imbasimba)!
  Now you can create all-sky FITS datasets that can be displayed in the latest
  release of the WWT engine. This includes a new routine to automatically
  determine the appropriate TOAST resolution level.
• A new -t option to toasty view allows you to view FITS data on remote
  systems using SSH tunneling (#87, @pkgw)! The tunnel mode uses SSH to tile
  the data on the remote machine, run a server, and tunnel the server to the
  local machine for display by your web browser.
• Finally, Toasty releases are now automatically deposited with Zenodo and
  assigned DOIs in the process. This makes it possible to cite the Toasty
  software, indicating exactly which version you were using, in scholarly
  context. The new command toasty show version-doi will display the DOI of the
  specific version of Toasty that you're running.

Some smaller improvements support these changes:

• Some of Toasty's internal systems were reorganized to allow for more efficient
  and flexible processing of pyramids (#89, #90, @pkgw). It is now possible to
  perform the "cascade" operation on sub-pyramids of data, allowing for parallel
  processing in HPC scenarios. A new toasty.pyramid.Pyramid data structure
  consolidates related code, reducing several nearly duplicate algorithms, and
  provides a more coherent formalism for treating operations on pyramids.
• Also, the code for filtering TOAST pyramids based on latitude/longitude bounds
  was fixed to work when the in-bounds area spanned more than 180 degrees, and
  also was made faster using Cython.
• Other efficiency improvements include:
  • Not writing all-flagged images (#88, @pkgw)
  • Avoiding creation of pyramid directories when reading imagery
  • Avoiding launching parallel operations when there is no work to do
  • Consolidating preparatory work for parallelized cascading
• When Toasty operations are being run in non-interactive scenarios, progress
  bars are now printed much more rarely and without screen overwrites, making
  for smaller and more readable log files (#88, @pkgw). This functionality is
  provided by a small new toasty.progress module.
• 16-bit integer images are now supported (#84, @imbasimba).
• DASCH FITS files with TPV distortions are now loaded with the correct LONPOLE
  setting.
