-Clean up of `detectors.py`: adds an `InterferometerStrainData` to handle strain data and `InterferometerSet` to handle multiple interferometers. All data setting should primarily be done through the `Interferometer.set_strain_data..` methods.
- InterferometerStrainData now handles both time-domain and frequencu-domaindata
- Adds documentation on setting data (https://monash.docs.ligo.org/tupak/transient-gw-data.html)
- Checkpointing for `dynesty`: the sampling will be checkpointed every 10 minutes (approximately) and can be resumed.
- Add functionality to plot multiple results in a corner plot, see `tupak.core.result.plot_multiple()`.
- Likelihood evaluations are now saved along with the posteriors.
### Changed
- Clean up of real data handling: all data is now windowed with a 0.4s roll off (unless set otherwise) and low-pass filtered.
- Add explicit method to create a power spectral density from time-domain data
- Clean up of `PowerSpectralDensity()` - addds `set_from` methods to handle various ways to define the PSD.
- Clean up of `detectors.py`: adds an `InterferometerStrainData` to handle strain data and `InterferometerSet` to handle multiple interferometers. All data setting should primarily be done through the `Interferometer.set_strain_data..` methods.
- Fix the comments and units of `nfft` and `infft` and general improvement to documentation of data.
- Fixed a bug in create_time_series
