Feature request: Limit of simultaneous connections

[MrMacStripe]

When using shared hosts some limit the amount of simultaneous connections to the server. For example, with the German hoster All-Inkl.com you can get an uncaught error:

FTPError: 530 Sorry, the maximum number of connections (10) for your host are already connected.

    at Socket.<anonymous> (/Users/mauricestuffer/WebDev/astro-boilerplate/node_modules/basic-ftp/dist/FtpContext.js:123:44)

    at TCP.onStreamRead (node:internal/stream_base_commons:190:23) {

}

A way to limit the connections / queue the uploads would fix this.
