SSR: tolerate floating point imprecision

[therealfrauholle]

I encountered a weird bug during SSR hydration on the client. I discovered the cause to be Math.cos within lat2tile not yielding the same results on the server and in my browser, a difference not bigger than floating point imprecision.

It appears the issue is related to the problem described here: https://stackoverflow.com/questions/26570626/math-log2-precision-has-changed-in-chrome

Without these changes, the following mismatched diff causes the hydration error.

+ position: "absolute"
- position: "absolute"
+ transform: "translate(6.019125609257912px, -138.1003211141433px)"
- transform: "translate(6.01913px, -138.1px)"
+ filter: ""
+ pointerEvents: "none"
+ cursor: "pointer"
- cursor: "pointer"
+ color: "black"
- color: "black"
+ transition: "color 0.2s linear"
- pointer-events: "none"
- transition-duration: "0.2s"
- transition-timing-function: "linear"
- transition-delay: "0s"
- transition-property: "color"

Note how the diff indicates that the transition property also indicates a problem (explicit vs. compact definition), but NextJS is actually able to understand that there is no issue in this case; the problem is solely caused by the arguably different transform values. This is why I believe this might be relevant for #168.

I also did some dogfood while I was on it, let me know what you think! And thank you for this awesome library 🚀
