The standard acos and asin functions use somewhat inaccurate approximations.
I found a better approximation over here: https://dsp.stackexchange.com/questions/25770/looking-for-an-arcsin-algorithm

Complexity is roughly the same, so computations shouldn't be slower with this.

Inlcuded is an .sbs with 2 function nodes:
- arcsin
- arccos

NOTE: Don't download this if you have SD 2019.2.2 or newer. The standard acos and asin nodes have been updated to use this better approximation.
