@i @tk @lain @piggo @sun found two issues benchmarking on my phone

1) pako (compression library we're using) takes 1 whole second to decompress the cache while it takes 65ms on desktop. I'm gonna try just not compressing and storing 5mb cache as is since we're using IndexedDB which doesn't have size restrictions.

2) it seems that cache isn't actually generated until theme is FULLY applied so rapidly refreshing always compiles the theme. Also will fix.
