Turf distance measurement doesn't match TurfJS
I am trying to port transformRotate from Turf.JS as I need it for a project.
In the method comments there are some examples with the expected result, my port didn't match. In trying to debug this I've noticed that the distance tests don't match between JS and the Java port.
The standard test points [-75.343,39.984][-75.534, 39.123] used the km distance in TurfJS is 97.12922118967835
Those same points are tested in the port but the expected result is different: 97.15957803131901
This third party suggests TurfJS is correct.
I've noticed Earth radius is different between the implementations so I guess this is the why
I see JS nearly changed to the same value for earth's radius but got reverted.
Is there a reason the port doesn't produce the same result as the original?
