v1.1.0 is broken in go1.16

Hi,

Thank you for this awesome project.

I'm getting the following error when importing the package in Go 1.16

../../go/pkg/mod/github.com/twpayne/go-polyline@v1.1.0/polyline.go:93:12: undefined: math.MaxUint
../../go/pkg/mod/github.com/twpayne/go-polyline@v1.1.0/polyline.go:94:10: undefined: math.MinInt

It seems there are some breaking changes in math package in recent Go versions.

Please let me know if you want any contribution from my end.

Thank you again.

Thanks for reporting this. #8 fixes it, and I've tagged v1.1.1 so you can go get the fixed version.
