rhdf5filters 1.26.0

H5Z_filter_blosc() and H5Z_filter_lzf() no longer expect outbuf_size in cd_values. This has no visible consequence for H5Z_filter_lzf() but requires shifting the parameters that previously followed it in H5Z_filter_blosc().

This package now compiles on Windows ARM. Thanks to Jeroen Ooms for reporting the issue and providing a patch.

This package now compiles on -std=c23. This was an issue in the bundled blosc library. Thanks to Alexander Bontempo for reporting the issue.
A R CMD check NOTE about bashims has been resolved.

This package no longer bundles the bzip2 compression library, and uses the system version instead. bzip2 is required by R itself so it is expected to be available on all systems.

Small changes to compilation of internal blosc and vbz libraries to cope with the C23 compiler becoming the default in R-4.5.0

Ensure PKG_CPPFLAGS are passed to all compilation step. This was an issue in the case where R was installed via conda and package binaries were not available. Backported to version 1.18.1.

rhdf5filters no longer sets the HDF5_PLUGIN_PATH environment variable when it is loaded. Instead this is handled by the H5PLprepend() function in rhdf5.

Fixed issue compiling VBZ filter when R was installed via conda. Backported to version 1.14.1. (Reported in https://github.com/grimbough/rhdf5filters/issues/20)

The package will now test for system libraries for several compression tools and will use those libraries rather than compiling from source if they are found.

Compression libraries updated:
- lz4: 1.9.2 🠪 1.9.4
Added the standalone Zstandard filter. The distributed version of Zstandard is now 1.5.5.
Added the VBZ filter.

Ensure ranlib is applied to the lzf library after it is compiled. This cause linking failures on some systems. (Thanks to Sergey Fedorov for the report https://github.com/grimbough/rhdf5filters/pull/18)

Compression libraries updated:
- blosc: 1.16.3 🠪 1.20.1
- lz4: 1.8.3 🠪 1.9.2
- zstd: 1.3.8 🠪 1.4.5
Added LZF filter

Fixed some missing references to CFLAGS, CPPFLAGS & LDFLAGS in package compilation (https://github.com/grimbough/rhdf5filters/pull/4)
Improved CPU detection on non-x86 architecture to allow compilation to proceed with default instruction sets, rather than failing to install. (https://github.com/grimbough/rhdf5filters/issues/3)
Address issue in compilation where message printed while processing .Rprofile where added to LDFLAGS (https://github.com/grimbough/rhdf5filters/issues/11) (#11)

Now passes R CMD config LDFLAGS to the compilation of the BLOSC filter. (https://github.com/grimbough/rhdf5filters/issues/2)
