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.
