Pyarmor

* Fix issue(644): build pyarmored wheel with the corresponding python tag and platform tag
* Fix issue: build wheel failed

* Enhancement(641): pyarmor as build-backend in pyproject.toml. Refer to [building pyarmored wheel](https://pyarmor.readthedocs.io/en/latest/build-wheel.html)

* Check the conflicts of option `--restrict 0` and `--with-license`
* Fix issue (628): super plus mode crashes if any function is patched
* Fix link errors in documentation
* Change core version to **r47.1**
* Support Python 3.10. For super mode, now only 3 platforms: windows.x86_64, linux.x86_64, darwin.x86_64

* Fix bug: there is no error message to run `pack` command with common debug option `-d`

A big feature [Super Plus Mode](https://pyarmor.readthedocs.io/en/latest/mode.html#super-plus-mode) is introduced in this version, and the format of license file for obfuscated scripts is changed.

Because the trial version uses the old core libraries, so it doesn't work with new license. When running the scripts which are obfuscated by trial version with option `--platform` or `--advanced`, it will raise exception: `Check license failed, Invalid input packet.`

* Fix issue (584): failed to run pyarmor in Cygwin
* Fix issue (586): In linux combining options both `--enable-suffix` and `--advanced 1` doesn't work
* Increase core version to **r46.20**
* Add sppmode, refer to [Super Plus Mode](https://pyarmor.readthedocs.io/en/latest/mode.html#super-plus-mode)
* Change the format of license file for obfuscated scripts and the old core libraries (before r46.20) doesn't work with new licenses.

* Fix issue (571): In Linux/Darwin super mode with `--enable-suffix` doesn't work
* Fix issue (584): In Cygwin pyarmor doesn't work
