New Release 1.2.0 (#26)
## Features
 * Can now parse files line by line in a fixed-size reading mode
 * Now has an option to ignore quotes when parsing

## Improvements
 * Speed increases in vanilla Lua and LuaJIT (benchmarks updated!)
 * Refactored code for easier maintenance

## Bugfixes
 * Better handling of multiple escaped quotes in vanilla lua (thanks @fredrikj83 #25)
