- Added `TREXIO_AUTO` back end for read-only mode (`r`) in PR #80
- Added unsafe mode (`u`) to `trexio_open`. When enabled, data can be
overwritten (using conventional `trexio_write`) and groups can be deleted 
(using new set of `trexio_delete_[group]` functions). Also added `unsafe` 
attribute to the `metadata` group to indicate that the file might be 
inconsistent. See PR #79
- Added `trexio_info` function (prints basic info about the library) in PR #78
- Added `trexio_inquire` function (checks validity of TREXIO files) in PR #75
- Fixed ISO_C_BINDING types in the Fortran API (`trexio_f.f90`) in PR #74 and #77
- Fixed code generation and some missing dependencies in CMake in PR #74
- Fixed portability issue with sed on MacOS so that `make python-install` works
- Clean `docs` folder only in the maintainer mode
