Version 4.0.0

This is a complete rewrite based with a Buffer implementation. There are no major breaking changes but it introduces multiple minor breaking changes:

• option rowDelimiter is now record_delimiter
• option max_limit_on_data_read is now max_record_size
• drop the record event
• normalise error message as {error type}: {error description}
• state values are now isolated into the info object
• count is now info.records
• lines is now info.lines
• empty_line_count is now info.empty_lines
• skipped_line_count is now info.invalid_field_length
• context.count is cast function is now context.records
• drop support for deprecated options auto_parse and auto_parse_date
• drop emission of the record event
• in raw option, the row property is renamed record
• default value of max_record_size is now 0 (unlimited)
• remove the record event, use the readable event and this.read() instead

New features:
* new options info, from_line and to_line
* trim: respect ltrim and rtrim when defined
* delimiter: may be a Buffer
* delimiter: handle multiple bytes/characters
* callback: export info object as third argument
* cast: catch error in user functions
* ts: mark info as readonly with required properties
* comment_lines: count the number of commented lines with no records
* callback: pass undefined instead of null

API management:
* Multiple tests have been rewritten with easier data sample
* Source code is now written in ES6 instead of CoffeeScript
* package: switch to MIT license
