Bump blosc2 from 2.7.1 to 3.0.0 in /etc/requirements_dependabot

[dependabot]

Bumps blosc2 from 2.7.1 to 3.0.0.

Release notes

Sourced from blosc2's releases.

Python-Blosc2 3.0.0 (final)

Changes from 3.0.0-rc.3 to 3.0.0

• A persistent cache for cpuinfo (stored in $HOME/.blosc2-cpuinfo.json) is now used to avoid repeated calls to the cpuinfo library. This accelerates the startup time of the library considerably (up to 5x on my box).

• We should be creating conda packages now. Thanks to @​hmaarrfk for his assistance in this area.

Release 3.0.0 rc3

Changes from 3.0.0-rc.2 to 3.0.0-rc.3

• Now you can get and set the whole values of VLMeta instances with the vlmeta[:] syntax. The get part is syntactic sugar for vlmeta.getall() actually.

• blosc2.copy() now honors cparams= parameter.

• Now, compiling the package with USE_SYSTEM_BLOSC2 envar set to 1 will use the system-wide Blosc2 library. This is useful for creating packages that do not want to bundle the Blosc2 library (e.g. conda).

• Several changes in the build process to enable conda-forge packaging.

• Now, blosc2.pack_tensor() can pack empty tensors/arrays. Fixes #290.

Release 3.0.0 rc2

Changes from 3.0.0-rc.1 to 3.0.0-rc.2

• Improved docs, tutorials and examples. Have a look at our new docs at: https://www.blosc.org/python-blosc2.

• blosc2.save() is using contiguous=True by default now.

• vlmeta[:] is syntatic sugar for vlmeta.getall() now.

• Add NDArray.meta property as a proxy to NDArray.shunk.vlmeta.

• Reductions over single fields in structured NDArrays are now supported. For example, given an array sarr with fields 'a', 'b' and 'c', sarr["a"]["b >= c"].std() returns the standard deviation of the values in field 'a' for the rows that fulfills that values in fields in 'b' are larger than values in 'c' (b >= c above).

• As per discussion #337, the default of cparams.splitmode is now AUTO_SPLIT. See #338 though.

Release 3.0.0 rc1

Changes from 3.0.0-beta.4 to 3.0.0-rc.1

General improvements

• New ufunc support for NDArray instances. Now, you can use NumPy ufuncs on NDArray instances, and mix them with other NumPy arrays. This is a powerful feature that allows for more interoperability with NumPy.

• Enhanced dtype inference, so that it mimics now more NumPy than the numexpr one. Although perfect adherence to NumPy casting conventions is not there yet, it is a big step forward towards better compatibility with NumPy.
