Development TypeCzech.js IMPORTED code for browser JSX and ESM

When in development, this large file replaces type-czech-import.js, 
providing all the type checking functions without any changes to the source code.

Used thus:
  import TypeCzech_obj from "./node_modules/type-czech/type-czech-import.js";
  const { TypeCzech } = TypeCzech_obj;
  const type_czech = TypeCzech(["CONSOLE-COUNT", "LOG-ERRORS"]);

const VERS_NUM = "version 1.7.5 2024-01-17";

/*
    TypeCzech contains:
      - Douglas Crockford's Cycle.js for working with cyclic variables
        https://github.com/douglascrockford/JSON-js/blob/master/cycle.js

      - Evgeny Poberezkin and James Hallidays fast-json-stable-stringify
        https://github.com/epoberezkin/fast-json-stable-stringify

    These two packages make mutation checking possible, and are included
    directly in this code to make it easier to use.
