Some little improvements and corrections. Especially puppeteer minor-version was restricted to avoid
possible chromium-version incompatibilities (note that `PUPPETEER_SKIP_CHROMIUM_DOWNLOAD` usually
has been set).

fix(debug): Instance-property `debug` was removed and replaced with a…

… static and global one

1. Imported `debug` (from 'debug') was exported totally to be fully accessible from the API.
    Also, Its mode was changed to be static, correctly. Instance-mode was a mistake.
2. debug-mode was disabled by default (`debug.disable()`). Even in `DEBUG` env-var presence.
    The consumer must be enabled it when needed.
3. "<@MODULE_NAME@>:" prefix was added to debuggers' namespaces.
    In this library it will replaced with "text-wrapper:" at build-time. See 'rollup-plugin-replace'

BREAKING CHANGE:
    1. Instance-property `debug` was removed and replaced with a static and global one

…n '\t' in the middle or the end

The length of TAB character is not fixed and depends on its offset (visualOffset). So the related
parts of the source was edited to implementing this feature correctly. The most important edited
part is `getVisualLength()` method.
