[Feature]: API access for password protected shares

Is your feature request related to a problem? Please describe.

Currently there is no way to access a public share which is password protected thorugh an automatism, because there is no way of supplying the share password into the API request.

Describe the solution you'd like

It could be implemented via a header, so when querying the URI you can provide all the neccessary information for gaining authorization in one go.

Describe alternatives you've considered

Alternatively i managed via IP masking, but there are many clients, and each time I want to pull the folder, i need to add its IP. Don't meantioning non-fix IP clients.

What are you using SFTPGo for?

Medium business

Additional context

Sensitive files are pulled to client machines from sftpgo, but don't want to expose these files on a bare public URL.
