@simonw documentation update to include examples for MS SQL

There may be a better way to show it and explain how it should be done, but I'm at a loss. The connection string for MS SQL with SQL Alchemy are just messy.

I also added headers to the connection string examples to separate them out and make it more clear which example went with which type of SQL.

This looks great!

The place you updated in the README is actually intended as a copy of the output of db-to-sqlite--help

I think this information would work better as a Markdown section in the README itself, similar to the "Using db-to-sqlite with PostgreSQL schemas" section.

Doh! 🤦🏻‍♂️

I’ll make an update to move it to its own section 😄

@simonw I made the updates to the documentation to have the MSSQL section separate based on your recommendation to use the "Using db-to-sqlite with PostgreSQL schemas" section.

I should have landed this a year ago! Thanks.

Thanks for getting this merged @simonw. Better late than never 😁
