improve test_jparse/is_available.sh

[lcn2]

We improve test_jparse/is_available.sh as follows:

• improve usage message
• add -w to print where the tool was found if a sane executable file
• does not assume type -P tool tests anything beyond existence
• perform sanity checks for: shellcheck picky independ seqcexit
• use bash best practices
• added detailed debug statements for -v 1, -v 3 and -v 5
• exit 0 after we are All Done!!! All Done!!! -- Jessica Noll, Age 2

Changed $IS_AVAILABLE_VERSION to $VERSION.

Changed test_jparse/is_available.sh VERSION from "1.0.0 2024-09-15" to "1.1 2024-09-15".

Performed the following tests:

test_jparse/is_available.sh ls
test_jparse/is_available.sh -v 3 -w ls

test_jparse/is_available.sh shellcheck
test_jparse/is_available.sh -v 3 shellcheck
