reading and writing coordinates doesn't return same values

[jtheuer]

$> echo '{"type":"LineString", "coordinates": [[10,52],[10.1,52.1]]}' | polyline --fromGeoJSON | polyline
[[-0.00002,52],[9.99998,52.1],[10.09998,52.09998]]

The rounding errors are probably by design but the coordinates are somehow corrupted.

polyline --fromGeoJSON and polyline --encode include leading and trailing quotes in the output, as if it were a JSON string, which means that output can't be piped directly back into polyline --decode. I think this is probably a bug, although fixing it would break any applications that expect the quotes. @nerik, as the original author of the CLI, what do you think?

Sorry for the late reply.
This is a bug, I think quotes should just be removed from the encoded polyline output - this is an easy fix. Maybe bump to a new major version?
Any other solution seems unclean to me: keep wrongly outputting quotes, adding some mechanism to detect leading/trailing quotes when using decode /toGeoJSON, but I'm happy to implement that too.
