feat(upload): add support on upload to topic

[XMLHexagram]

close #500

[XMLHexagram]

@iyear I add both --topic flag and --to flag.

In this PR, users can use tdl up -c @foo --topic xxx as a legacy but convenient way to upload file to topic.

Or users can use --to and expr, for example, tdl up --to '{ Peer: "@foo", Thread: xxx }' to get the same result.

I wonder if this is a good practice to have two way to get the same goal, or just marking -c as deprecated and only reserving--to is a better solution?

(In my option, it is better if tdl can provide both a convenient way and an advanced way.)

I will update docs after you decide which way is better.

Looking forward to your reply.

Any updates regarding this?

Updates? Recently I need to upload a lot of files to my personal group that has a few threads, found out tdl does not support it yet, this looks great.
