Depwarn caused by non-deprecated entry point `exe`

With --depwarn=yes

julia> FFMPEG.exe("-version")
┌ Warning: ffmpeg() is deprecated, use the non-do-block form

Also, I think this is more confusing than it needs to be https://github.com/JuliaPackaging/JLLWrappers.jl/issues/59

Yes, I'm wondering how to get rid of this message too:

┌ Warning: ffmpeg() is deprecated, use the non-do-block form
│   caller = ip:0x0
└ @ Core :-1

using FFMPEG.jl 0.4.1.

I believe that's already fixed by #47, but there haven't been new releases for over 3 years.

Closed as we just made a new release
