add numerous functions, remove WSL functions

distinguish absolute() and resolve()

add get_shell(), handle2filename(), hard_link_count(), is_rosetta(), root(), root_name(), file_size(), drop_slash(), is_prefix(), cpu_arch(), os_version(), java_vendor()

ci: add jobs without Java VM "-nojvm"

CI: auto-publish inline documentation

benchmark Java vs. non-Java under example/ directory

all functions default to not use Java, except functions that are only implemented in Java

Most functions GNU Octave compatible

Numerous speed and correctness improvements

CI: test java/non-java for each function so capable.

Remove WSL functions

Test:implement with parameterization for best practice
