v0.2.0 (2022-05-22)

Changes from v0.1.0 to v0.2.0:

MAJOR Made ind_start and indices have different data types in CRS, CCS, and HIF. In particular, HIFIR library now uses std::ptrdiff_t for ind_start and int for indices. This change doesn't break some high-level APIs (such as factorize(A)), but it potentially breaks wrap_const_crs and wrap_const_ccs interfaces.
Repurposed read_bin and write_bin to use HDF5 backend if users turn on derivative HIF_HAS_HDF5 during compilation.
Removed interval compressed storages and ASCII I/O for sparse matrices.
Fixed the issue regarding modifying user-input data in preprocessing calling equilibration.
Changed I/O to use local buffers instead of shared ones and removed writing to warn_flag at the beginning of factorizations.
Made logging system more complete.
Added C library libhifir.
Updated documentation for the C interface.
Added MatrixMarket file readers for the C library.
Added example code for libhifir.

This is the initial official release of the HIFIR package.
