Dcc send files

[JasonWMcKee]

Added DCC functionality to core

Description

Added the ability to send files with the DCC protocol.

Test Plan

I created I quick plugin

from cardinal.decorators import command, help

# File to be sent
FILE_PATH = "/tmp/test.txt"

class DCCSendPlugin:
    """Plugin to handle !sendfile command and send a file via DCC SEND."""

    @command(["sendfile"])
    def send_file(self, cardinal, user, channel, msg):
        """Sends /tmp/test.txt to the requesting user via DCC SEND."""
        cardinal.senddccfile(user, FILE_PATH)
        cardinal.sendMsg(channel, f"{user}: Sending test.txt via DCC SEND.")

entrypoint = DCCSendPlugin

I just realized I should have tested large files to ensure the timeout doesn't supersede the transfer
