more improvements as child project

avoid conflicts with building HDF5, linking MPI, detecting Python, etc.

improvements as child project

• improve test coverage
• warn instead of fail config if path problem--use CTest phase to catch this instead
• make h5fortran_BUILD_TESTING to allow parent project control

Autobuild HDF5 if needed, CMake >= 3.19

• Autobuild HDF5 and ZLIB if needed
• cmake -Dfind=on by default, set off to not search for HDF5
• CMake >= 3.19 required for robustness

numerous bugfixes for character, improve CI

v4.10.3

badge

bugfix datatype, CI valgrind

v4.10.2

verify CMake 3.11+ compatibility

Cpack correct parameters

v4.10.1

cpack: correct parameters

character dataset/attribute 0d..7d

Previously, fixed/variable character were only scalar reads. Now, scalar through 7D character arrays can be read for datasets and attributes, fixed/variable. Writing was already enabled.

Add bounds checks and unify with h5fortran-mpi.

Add ability to cast on read from real to int and int to real

Internal efficiency improvement. Add attribute character array write

also work with CMake 3.11+

default action='r', remove open(verbose=)

• remove little-used %open(verbose=) which is subsumed into %open(debug=)
• default %open(action=) was undocumented but was long default to 'rw'. As a better practice in accord with h5py, default %open(action='r') is now default and documented
