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

Erica Fischer 073700aa38 Reduce maxzooms being guessed a little: (#2)
* Reduce maxzooms being guessed a little:

* Use 1.5 standard deviations, not 2, as the minimum distinguishable
* Give overlapping polygons and linestrings more distinct indices

* Add another drop rate guessing options, from the same metrics -zg uses

* Guard against using -rp without -zg

Erica Fischer a447dfc089 Extra coordinate precision; feature ordering; compression improvements
* Add an option to retain extra coordinate precision at maxzoom

* Make sure not to shift away the extra detail from coordinates

* Add an option to convert double-precision attributes to single

* Sort attribute values in tiles to make them compress a little better

* Slightly improve polygon simplification

By choosing a point that would be retained after simplification
to be the start/end point that always gets retained

* I regret making all of these tests involve polygons

* Add an option to specify the size of tiny polygons

* Fix accidental requiring of argument for --single-precision

* Guard against duplicate points when generating "sizes" for them

* Restore the intended behavior that tiny polygons don't get simplified

* Make the extra detail settable rather than always maximizing it

* Revert "Improve maxzoom guessing for tightly-clustered point data sources (#4)"

This reverts commit fec5e8354c.

* Add an option to prevent choosing a base zoom higher than the maxzoom

* Keep the drop rate high enough when the basezoom gets constrained

* Revert "Revert "Improve maxzoom guessing for tightly-clustered point data sources (#4)""

This reverts commit db6bc27d9e.

* Add --order-by and --order-descending options

* Accept multiple --order-by and --order-descending-by sort keys

* Add missing #include

* Don't preallocate as much space for arrays and objects

* Treat inability to check free disk space as a warning, not an error

* Update changelog and version
