v5.0.0

=====================================================================

Excited to bring V5 to life. This includes some BREAKING CHANGES to
several aspects of ZSH-type scwrypts. Please refer to the readme
for upgrade details (specifically docs/upgrade/v4-to-v5.md)

--- New Features -------------------------

- ZSH testing library with basic mock capabilities

- new scwrypts environment file format includes metadata and more
  advanced features like optional parent env overrides, selection
  inheritence, and improved structurual flexibility

- speedup cache for non-CI runs of ZSH-type scwrypts

- ${scwryptsmodule} syntax now allows a consistent unique-naming
  scheme for functions in ZSH-type scwrypts while providing better
  insight into origin of API calls in other modules

- reusable, case-statement-driven argument parsers in ZSH-type scwrypts

--- Changes ------------------------------

- several utility function renames in ZSH-type scwrypts to improve
  consistency

- documentation comments included in ZSH libraries

- ZSH-type scwrypts now allow library modules to live alongside
  executables
  (zsh/lib still supported; autodetection determines default)

--- Bug Fixes ----------------------------

- hardened environment checking for REQUIRED_ENV variables; this removes
  the ability to overwrite variables in local function contexts
