Version 2.2.9

This version adds many new features and improvements, the highlights are:

• New uvh5 version with support for multiple phase centers.
• Support for future array shapes in UVFlag.
• More comprehensive support for the SMA's MIR format.
• Reordering methods for UVCal.
• UVFITS parameters RDATE, UT1UTC and GSTIAO are now properly calculated.

It also fixed a number of bugs including:

• A bug in UVData.__add__ with flexible spectral windows that contain overlapping frequencies.
• A bug in UVData.select when UVData._scan_number_array was set.
• A bug in UVBeam.select when selecting down to only auto polarization power beams.
• A bug in UVBeam.__add__ when adding cross pol power beams to auto pol power beams.

Deprecations and dependency version changes:

• The "unphased" cat_type in phase_center_catalog is now called "unprojected".
• Dropped support for python 3.7
• New minimum dependencies: astropy>= 5.0.4, numpy>=1.19, scipy>=1.3
• New minimum optional dependencies: python-casacore>=3.3, pyyaml>=5.1, astropy-healpix>=0.6
