deps: update netcdf4 requirement from >=1.6.0 to >=1.7.2

[dependabot]

Updates the requirements on netcdf4 to permit the latest version.

Changelog

Sourced from netcdf4's changelog.

version 1.7.4.1 (tag v1.7.4.1rel)

• Change default encoding for stringtochar/chartostring functions from 'utf-8' to 'utf-8'/'ascii' for dtype.kind='U'/'S' (issue #1464).
• Fix DeprecationWarning for assigning to numpy.ndarray.shape for numpy >= 2.5.0 (issue #1468).
• Disable parallel support even if libs support it via DISABLE_PARALLEL_SUPPORT env var (issue #1389).

version 1.7.4 (tag v1.7.4rel)

• Make sure automatic conversion of character arrays <--> string arrays works for Unicode strings (issue #1440). (previously only worked correctly for encoding="ascii").
• Add netcdf plugins (blosc, zstd, bzip2) in wheels. Blosc plugin doesn't work in Windows wheels. Macos wheels now use conda provided libs. (PR #1450)
• Add windows/arm (PR #1453) and free-threaded python wheels (issue #1454). Windows wheels now use netcdf-c 4.9.3. WARNING: netcdf-c is not thread-safe and netcdf4-python does have internal locking so expect segfaults if you use netcdf4-python on multiple threads with free-threaded python. Users must exercise care to only call netcdf from a single thread.

version 1.7.3 (tag v1.7.3rel)

• Python 3.14 wheels (issue #1432)
• support os.PathLike arguments for Dataset.fromcdl and raise a FileNotFoundError if the cdl is missing and a FileExistsError if the nc file already exists (PR #1387)
• raise more informative error when trying to iterate or perform a membership operation on a Dataset (issue #1383)
• fix type hint for createEnumType (issue #1378)
• add python 3.13 to windows wheel builds (PR #1377)
• allow slicing of vlen and string variables with non-unitary strides (issue #1408).

version 1.7.2 (tag v1.7.2rel)

• add static type hints (PRs #1302, #1349)
• Expose nc_rc_set, nc_rc_get (via rc_set, rc_get module functions). (PR #1348)
• Add Variable.get_fill_value and allow fill_value='default' to set _FillValue attribute using default fill values. (issue #1374, PR #1375).
• Fix NETCDF3 endian error (issue #1373, PR #1355).

version 1.7.1 (tag v1.7.1rel)

• include nc_complex source code from v0.2.0 tag (instead of using submodule).
• add aarch64 wheels.

version 1.7.0 (tag v1.7.0rel)

• add support for complex numbers via auto_complex keyword to Dataset (PR #1295)
• fix for deprecated Cython DEF and IF statements using compatibility header with shims for unavailable functionality (PR #1277)
• use szip as the library name on Windows (PR #1304)
• add support for MS-MPI MPI_Message detection (PR #1305)
• fix for issue #1306 - surprising result when indexing vlen str with non-contiguous
