CSV parsing implementing the Node.js `stream.Transform` API

# Changelog

## Version 4.0.2

* security: remove regexp vulnerable to DOS in cast option, npm report 69742

## Version 4.0.1

Fix:

* relax_column_count: handle records with more columns

## 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
