Prep for new release targeting the upcoming HPS 1.3

[FedericoNegri]

Prep in view of a new release targeting the upcoming HPS 1.3.

• Adding v1.3.45 as HPS version we can run tests against

• Updated the compatibility table (last row and last column are new)
  

• Added backward compatibility tests to make sure that the current PyHPS is still compatible with HPS 1.2 as documented. This is true apart for:

  • task definition template changes
  • debug field in the task definition
  • changes to output parameters

  Modified the tests to report explicit version dependent expected failures. Reasons for additional skipped/x-failed tests are reported in the pytest summary

Reviewed the changes, very happy that you go all the efforts on version compatibility, even adding backward compatibility tests.
