integrate kamal directions - part 1

[carocad]

part of #74

This is by no means a complete integration. However, after trying to integrate it I realised that there are several pieces of information missing in kamal's response.

So for the time being I think it suffices to just review what I currently have and then work again on it once we change kamal.

CHANGES:

• put View styles directly as prop without :style keyword. It seems to be accepted only for that component
• fixes #101 -> http/json and tool/channel now take a seq of transducers instead of a single one
• use provided Google Closure Library to handle DateTime and duration
• removed directions spec for parameters that we have not implemented
• draw geometry on the map
• provide an overview for the direction steps

PS: I also did some small changes in the build script since it started failing for some reason. My guess is that the latest expo release broke it.

PS2: you will need a local kamal instance running for the app to be usable. You could also have a remote container running but right now is hardcoded to localhost

@carocad starting a local kamal did not change anything. The app runs, I see the new direction icons in the bottom but nothing else.

Unfortunately currently the http function that I use is configured to ignore errors, and I think the IP was hard coded to match my network so you need to change that :(

We need to change our error strategy in the app but since react native needs special handling for that I haven't implemented it
