expand testing, enable compression, add methods

• add methods: is_chunked, is_contig, chunks
• enable compression with auto-chunking
• expand testing like h5fortran

better feature parity and testing like h5fortran

add netcdf_file methods:

• read_attribute
• write_attribute
• ndims
• flush

add functions

• nc_exist
• is_netcdf

allow variable rewrite. Numerous bugfixes

use reader, writer templates

due to the high level of code duplication across array rank (dimension), we use CMake or Meson configure_file() to simply inject this code for each dimension. This makes the program more robust. If we instead used Fortran select rank we would still need a template, and it wasn't immediately clear there would be a benefit from this vs. the current approach.

make more robust, add properties

add properties:

• status='scratch' a file that will be deleted on close, for file-based API
• h%is_open is the file opened, this is used internally to give errors if user tries to access file before initializing or after finalizing

Make CMake build and run tests in parallel.

quality, robustness

• implicit none (type, external)
• use native CMake functionality instead of custom

add CDash, increase build robustness

v0.4.3

implicit none (external)

quiet pkg-config, correct error message text, gcc 9.3.0 dedupe

v0.4.2

remove duplicated use for gcc 9.3.0

name write(..., dims=['x','y']) parameter

v0.4.1

name dimnames dims for conveninence in write()

add %exist('/foo') method, bugfix

add verbose param and exist check

bugfix api

ierr optional, add tests

Like h5fortran, nc4fortran ierr parameter is now optional. If an error occurs and ierr is not present, nc4fortran will raise error stop.

increased test coverage and modularized test coverage

reduced redundant code
