Deprecation and/or removal of resdata applications

[berland]

The applications in resdata/applications/resdata installed through setup.py serves various purposes. Some of these should be deprecated and/or possibly removed:

• CF_dump: Any user of this is better of using res2df and its rft module, that extracts the same information and more
• convert.x: This might have some use cases, but could be deprecated in favour of a recommentation to use resfo instead.
• rd_pack.x/rd_unpack.x: This is used by subscript's restartthinner. If subscript uses resfo instead, we can deprecate it.
• grdecl_grid: Should be deprecated or outright removed. It parses input decks, but very poorly. And then it does nothing.
• grdecl_test: Times the loading of a grdecl-file. Limited use for this, deprecate.
• grid_dump.x/grid_dump_ascii.x: Prints xyz for all 8 corners of every cornerpoint-cell. Has probably limited use-cases. Deprecate.
• grid_info.x: Will print some simple aggregated numbers for a grid. Attainable in short lines of python from res2df also. Can also compare two grids. for equivalence. Can probably be replaced by res2df and pandas.
• kw_extract: Can seemingly extract summary vectors (?) from one file and inject it into another file. Very unclear why anyone would like to do that. Propose to deprecate.
• make_grid: Makes a dummy cartesian grid. Only useful in a test-suite. Deprecate.
• ri_well_test: Loads a file "similar" to how resinsight is loading it. Would fit as an integration test, but resinsight is not using this codebase any longer so serves no purpose. Remove.
• segment_info: This data is much better presented by res2df rft. Deprecate.
• select_test.x: Seemingly a dummy binary that does nothing (could be part of the test suite). Remove.
• summary.x: The most famous application from resdata, and might still have users. Recommended to use res2df summary instead. Deprecate.
