Add ability to quote all output

[moorereason]

The Problem

I need to be able to quote all headers and values in the output in order to maintain compatibility with another system. AFAIK, csvtk doesn't currently support his.

Reproduction

Given input file x.csv:

"A A","B","C","D"
"1","  2","3  ","4"

Given command:

csvtk sort x.csv

csvtk outputs:

A A,B,C,D
1,"  2",3  ,4

The desired output should be the same as the input file.

Workaround

I'm currently using miller as a workaround:

csvtk sort x.csv | mlr --csv --quote-all --no-color cat

Sorry, csv.Writer does not support that.
