Writing vector tiles

[mourner]

It needs an API to write a vector tile dynamically from JS into PBF.

@mourner Do you know if there's been any work on this already? I think I may need this in a few weeks, so I was gonna start up a PR, but don't want to duplicate..

Did this here: https://github.com/anandthakker/vt-pbf

@anandthakker, @mourner, @jakepruitt I have made a proposal on how to encode objects (hstore) and arrays as values at mapbox/vector-tile-spec#75 (comment) , and as part of a trial implementation, I need to take a vector tile, decode it in JS, reorganize tags, and save it back. I do not need to touch geometries. I see there was a few efforts to do it, like @jakepruitt https://github.com/mapbox/vector-tile-js/compare/serialize branch, and the one by @anandthakker above. What is the status of it? Any interest in doing it soonish? Thanks!

I think we should merge vt-pbf into this library.

I'm already using PBF-re-writing functionality (without geometry modifications) in the https://github.com/kartotherian/babel library - it converts JSON blob (single string in one field) into multiple fields - e.g. name_: "{en:xxx, ru:yyy, fr:zzz, ...}" into name_en:xxx, name_ru:yyy, name_fr:zzz, ...
