[FeatureRequest] Automated planetary gear system generation

[VinnyCordeiro]

The add-on already have the capacity to generate both external and internal involute gears. Creating a planetary gear system is possible but is very hard, due to all problems that need to be solved for a proper design (the load division between planet gears, the interference of the internal gear, the balance and vibration of the rotating carrier, the hazard of jamming, etc.).

The linked reference on README.md, Elements of Metric Gear Technology, already have the necessary information for a proper design (page T61 and T62), and there are online tools that already do that: https://www.thecatalystis.com/gears/, showing that this feature can be done.

Appreciate your time and effort, this add-on is very, very useful.

thanks @VinnyCordeiro . A planetary gear calculator would be a nice addition, but not something I will work on in near future. If someone wants to add this functionality, please go ahead and create a PR.
