2.6.10

Added:

• Building of Python package wheels using cibuildwheel has been added as a GitHub Actions workflow, making use of the change in build system (see below).

Changed:

• The build system has been updated to use pyproject.toml + scikit-build-core for the Python package, replacing the legacy setup.py + setuptools system of yore. As a result, the CMake build procedure has changed a bit, notably in that building a Python wheel using CMake is no longer supported. Use python -m build or an equivalent frontend from the source root to build Python wheels instead. The Python package can still be built and installed as before using CMake, just not as a wheel.
• When reading Digital Metadata, convert numpy object arrays to a list for better interoperability (particularly with GNU Radio's PMT type). Also ensure that arrays of strings have the str type.

Removed:

• Python 2 and Python < 3.8 will no longer be supported, and the README and build system has been updated accordingly.
• The dependency on pytz has been removed in favor of equivalent functionality now in the Python standard library.

Fixed:

• Replace deprecated use of Python datetime's utcnow() and utcfromtimestamp().
• Fix CMake so that digital_rf.dll actually gets installed on Windows! This makes the C library usable independent of the Python bindings.
• Fixed TypeError: unsupported operand type(s) for /: 'int' and 'numpy.longdouble' issue with gr_digital_rf.digital_rf_channel_source by converting the int to a numpy.uint64 before division.
• Fixed aliased numpy function names for numpy 2.0 compatibility.
• Updated to numpy 2.0's new definition for the copy keyword for np.array() by switching to np.asarray() as suggested.
