iocore 3.1.0

IOCore is a safe library for unix CLI tools and Systems programming. IOCore provides the [`iocore::Path`] abstraction of file-system paths designed to replace most [`std::path`] and [`std::fs`] operations with practical methods, other abstractions include: - handling file-system permissions via [`iocore::PathPermissions`] powered by the crate [`trilobyte`]. - handling file-system timestamps via [`iocore::PathTimestamps`] granularly via [`iocore::PathDateTime`]. IOCore provides the [`iocore::walk_dir`] function and its companion trait [`iocore::WalkProgressHandler`] which traverses file-systems quickly via threads. IOcore provides [`iocore::User`] which provides unix user information such as uid, path to home etc. The module [`iocore::env`] provides [`iocore::env:args`] returns a [`Vec<String>`] from [`std::env:args`], and [`iocore::env:var`] that returns environment variables as string.
