Non-bats testing and repo structure update

[underwoo]

Description
Updated the land_utils application testing so it does not require bats.
Included with this is a new testing framework, which was acquired from
GNU coreutils. This testing framework, while less extensive than
bats, has several built-in features that improve the testing process.

This update also begins the migration of the utilities out of the
postprocessing and tools directories.

Additional fixes in this PR:

• Use --tags option to git describe to use any tag, not just annotated tags.
• Add --version options to applications that did not have that option
• Developed a standard version of text, and allowed it to be callable from C and Fortran applications
• Fixed land_utils testing to use a compressed land file

Fixes #320 and #321

How Has This Been Tested?
Testing was performed on an Intel Mac, using homebrew for required
libraries (e.g., netCDF) and using make check. I also tested several Linux systems with different OSes (ubuntu and rocky 8).
