Add a svg export with proper rounding (#58)
* make live version render single-point paths the same as preview does

* implemented smoothing in server side rendering

* separate preview from export

* ensure correct handling of paths with only one child

* break out rendering of 3rd point and up into separate function

* changed test for 2 points to math current implementation and added a test for a bezier curve with 3 lines

* deduplicate code to extrapolate points for bezier curves

* fix merge

* Factor more code between the client and the server

Completely remove the straight line approximation foor paths

Vastly improve preview performance

* Add support for opacity in preview

* Stream board previews to the browser

Previously, svg board previews were generated in memory
and then pushed to the client.

They are now streamed to the client without blocking the main thread.
