To fix issues with floating-point precision we've made use of Google's double-conversion lib to handle conversions of doubles to and from strings. In addition to fixing our precision problems this will improve double encoding by 4-5x. Decoding is however slightly slower according to the benchmarks - but accurate at least. This change removes the double_precision encoding option and the precise_float decoding option.
