/** Reads and writes comma-separated values (CSV) files.
*
* There are many kinds of CSV files; this module supports the format described
* in {@link https://tools.ietf.org/html/rfc4180 | RFC 4180}.
*
* A csv file contains zero or more records of one or more fields per record.
* Each record is separated by the newline character. The final record may
* optionally be followed by a newline character.
*
* ```csv
* field1,field2,field3
* ```
*
* White space is considered part of a field.
*
* Carriage returns before newline characters are silently removed.
*
* Blank lines are ignored. A line with only whitespace characters (excluding
* the ending newline character) is not considered a blank line.
*
* Fields which start and stop with the quote character " are called
* quoted-fields. The beginning and ending quote are not part of the field.
*
* The source:
*
* ```csv
* normal string,"quoted-field"
* ```
*
* results in the fields
*
* ```ts
* [`normal string`, `quoted-field`]
* ```
*
* Within a quoted-field a quote character followed by a second quote character is considered a single quote.
*
* ```csv
* "the ""word"" is true","a ""quoted-field"""
* ```
*
* results in
*
* [`the "word" is true`, `a "quoted-field"`]
*
* Newlines and commas may be included in a quoted-field
*
* ```csv
* "Multi-line
* field","comma is ,"
* ```
*
* results in
*
* ```ts
* [`Multi-line
* field`, `comma is ,`]
* ```
