sql: Add support of escape quote in CSV (#9231) 
This commit modifies csv parser, a fork of golang csv
parser to support a custom quote escape character.

The quote escape character is used to escape the quote
character when a csv field contains a quote character
as part of data.

c9b8bd8de2 S3 Select: optimize output (#8238) 
Queue output items and reuse them.
Remove the unneeded type system in sql and just use the Go type system.

In best case this is more than an order of magnitude speedup:

- New parser written from scratch, allows easier and complete parsing
  of the full S3 Select SQL syntax. Parser definition is directly
  provided by the AST defined for the SQL grammar.

- Bring support to parse and interpret SQL involving JSON path
  expressions; evaluation of JSON path expressions will be
  subsequently added.

- Bring automatic type inference and conversion for untyped
  values (e.g. CSV data).
