Allow quotes in TOML comments

[bglw]

Currently the TOML narrator package produces bad output on lines like the following:

title: "Hello World" #: A "simple" title

where it produces:

title--bookshop_comment = "A "simple" title"
title: "Hello World" #: A "simple" title

but it should produce:

title--bookshop_comment = "A \"simple\" title"
title: "Hello World" #: A "simple" title

For the correct output should it not be...

title--bookshop_comment = "A \"simple\" title"
title = "Hello World" #: A "simple" title

Yes indeed it should be. YAML brain strikes again.
