Does `software::scaling::context::Context` not implement `Send` for a reason?

[tdgne]

I am not that familiar with ffmpeg, but I thought it'd be useful to have software::scaling::context::Context implement Send just like software::resampling::context::Context does here if possible.

There is an open pr for this at #85 btw
