[MSSQL] Database name is not decoded from URL encoded connection string

What language are you using?

Rust

What version are you using?

v0.4.0

What database are you using?

Microsoft SQL Server

What dataframe are you using?

Arrow

Can you describe your bug?

In MS SQL Server, database names can contain a space, e.g. My Database or [My Database]. After a url::URL struct is created from the connector-x connection string, the database name (path) is not decoded which results in a database name that cannot be found.

My%20Database instead of "My Database".

What are the steps to reproduce the behavior?

Minimal example using only the url and urlencoding crates:

    let url_str =
        "mssql://sa:Welcome_123@localhost:1433/My Database?xcprotocol=binary&encrypt=false";
    let url = url::Url::parse(url_str).unwrap();

    println!("{}", &url.path()[1..]);
    println!("{:?}", urlencoding::decode(&url.path()[1..]).unwrap());
}

What is the error?
