- Provides backward compatibility for people with scripts using the old
  style
- Also because, as Colm pointed out, there may be bugger behaviour with
  multiple detectors and it may take a long time to calculate the waveform
- Change the name in `inject_signal` from
  waveform_polarizations->injection_polarizations.

This last step could break peoples code who are using inject_signal
directly, but its probably best to unify notation now rather than have
two names for one thing.

This reverts commit 2ab4bddd.

For some reason, the list comprehension method of setting the IFOs
intereacted badly with the example_test method. This doesn't change
anything, but just makes it a straightforward for loop.

Also removes the failing detector tests.

Closes #116

- Changes the warning to an Error
- Adds method to InterferometerStrainData to check if a time is within
  the span
- Clean up logging of warning if the geocent_time is within the data
  span
- Print infomation about the injection to the terminal

Closes #115

Adds the option to add a label to the saved data and plots associated
with Interferometer

Adds explicit method to convert floats to delta functions

See merge request Monash/tupak!80

- Move logic from `fill_prior` to its own method
- Call in `sample` to ensure the full set is sampled
