Accept csv generate options hash

[alessandro-fazzi]

Problem

As far as I understood, it's not possible to configure how the csv file will be generated.

My personal use case is to be able to export a CSV with custom column separator.

Proposal

Introduce a new option called csv_generate_options; this is a Hash. This will be passed down to the CSV.generate call, thus accepted options are the same as ones accepted by the CSV class.

Here's the ref: https://ruby-doc.org/3.2.1/stdlibs/csv/CSV.html#class-CSV-label-Options+for+Generating

The option will be configurable as other options are:

• csv_generate_options parameter passed to .to_csv method
• SPREADSHEET_OPTIONS global config
• SpreadsheetArchitect.default_options global config

This PR is a draft ATM because:

• i'd like to know if maintainer(s) would be interested to introduce the feature
• the implementation is not yet tested
