Updates netcdf4 from 1.7.4 to 1.7.5.1.post1

Changelog

Sourced from netcdf4's changelog.

version 1.7.6 (not yet released)

• Speed up index setup in _StartCountStride (used when indexing variables) by skipping numpy conversion for plain ints and slices and classifying each index once (PR #1524).

version 1.7.5.1.post1 (tag v1.7.5.1.post1rel)

• fix installation of plugins into linux wheels.

version 1.7.5.1 (tag v1.7.5.1rel)

• make sure zstd compression filter test always runs unless specifically disabled, fix cli test so it runs on 32-bit x86. New wheels for linux that include plugins (they were left out of the 1.7.5 release).
• fix version comparison logic that was broken when using netcdf-c >= 4.10.0 - this was the cause of issue #1515 (diskless persisted datasets are no longer persisted).

version 1.7.5 (tag v1.7.5rel)

• remove python 3.10 support (it reaches EOL October 31, 2026).
• Reject fractional scalar indices instead of silently truncating reads or writes (issue #1350).
• Preserve surviving dimensions and decoded types for empty orthogonal selections, including empty integer indices and all-false masks (PR #1499).
• Convert non-native-endian numeric attributes to native byte order before writing (issue #1502).
• Fix command-line usage error exit codes and --help handling, honour nc4tonc3 --chunk, and fix ncinfo group dimension selection (issue #1500).
• 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)
