fix(tohtml): enclose font-family names in quotation marks

Font-family names must be enclosed in quotation marks to ensure that
fonts are applied correctly when there are spaces in the name.

Fix an issue where multiple fonts specified in `vim.o.guifont` are
inserted as a single element, treating them as a single font.

Support for escaping commas with backslash and ignoring spaces
after a comma.
