inflate tiles natively

[jpilet]

currently, tiles are decompressed from the sqlite database in the main javascript thread.

It would be faster to decompress natively using a cordova plugin, or even a sqlite C function.

The inflate call is here

In previous versions the decompression was made in a worker thread:
https://github.com/oscarfonts/mapbox-gl-cordova-mbtiles/blob/v0.0.6/src/mbtiles_worker.js#L10

A later contribution merge moved the decompression to the main thread, and there it is. It may be a good idea to move the decompression back to the worker.

Indeed, it would be even better to support native decompression. Would you give it a try? ;)
