Erica FischerandRoman Karavia 182093bdc7 Improve precision of polygon area calculations (#19) ...

* Improve precision of get_area by using long double

* Trying to get consistent polygon area results between ARM and x86

* Calculate polygon area closer to the origin for better precision

* Update changelog

* Also exercise tiny polygon dust in the ring area test

They previously behaved differently here between x86 and ARM

* On M1 Macs, long double is just double anyway, so don't use it

* Be more careful about overflow: scale the polygon ring down into range

* Fix the bug I just introduced in the scaled area calculation

* Use only the sign from the scaled-down area calculation
