Allow parsing contest

[qixiao986]

When I start neovim, CphReceive one problem is ok, but if I CphReceive another problem, it does nothing, I have to restart the neovim and it receive again. looks like it can only receive one problem in one session.
I check the source code, find here:

cphelper.nvim/lua/cphelper/receive.lua

Line 37 in 7d18ff6

M.server:shutdown()

looks like the server didn't close like the client, so I add this:
M.server:close()
and it worked properly.
please check if this is a bug.

or we can move this line out of the function and don't close, that will receive multi problem without retype CphReceive, that's very handy.

cphelper.nvim/lua/cphelper/receive.lua

Line 9 in 7d18ff6

M.server = uv.new_tcp()

Keeping the server on would be a waste of resources right?

yeah, but to me it's very convenient and more suits my needs.

It takes like 1 second to :CphReceive again (write :Cp and tab through), so I won't change this. I added M.server:close() and fixed the issue, thanks!

I have another reason why we should keep server open, if we want parse contest, that will need us to receive multi problem at once, if the server close it can only receive the first problem. you can try to parse a codeforces contest, like this link:Codeforces Round #779 (Div. 2)
