Added support 32-wind compass rose

[alex-w]

Description

Currently we have support 8-wind and 16-wind compass rose (used in navigation and meteorology). I've added support 32-wind compass rose as an additional to Navigational Stars plugin for navigational purpose.

Type of change

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to change)
• This change requires a documentation update

How Has This Been Tested?

1. Run Stellarium
2. Enable cardinal points
3. Enable 8-, 16- and 32-wind compass rose

Is it actually useful? I do realize that these names exist, but IMHO at some point naming ever smaller sectors becomes more cumbersome than simply using numeric azimuth.

1/32 of the full circle is an (outdated?) nautical directional unit ("Strich" in German; sorry, I cannot find an English reference for this! Google translate has "dash". A similar concept with smaller units is the artilleristic 'mil' (6400 parts to the circle, or 6000 in former Soviet-influenced states). There are nautical commands like "Ruder zwei Strich backbord" (Turn rudder to change course by two of these 1/32 units to the left"). So yes, this is the last partition that may make sense. Maybe even extend this in yet another option to not use these names but show all these directions with the proper unit sign like 16" for "due south".

Yes, but for navigational purposes and partially for marine astronomy. By default these labels are disabled and probably for low count of users this feature will be extra useful (sailors), but this is final part for standard marine/navigational compass points, so, all navigational data is complete now.

Russian: румб :) These directions still uses by sailors for example.

Ah, that brought me to the English term: https://en.wikipedia.org/wiki/Rhumb

OK for me.
