LUT support

[efati]

I would love to have direct support for LUT-s (3D lookup tables) in SMPlayer. Currently it is possible to load them by modifying Preferences –> Advanced –> MPlayer/mpv –> Options:

--lut=/path/to/my.cube

However, you cannot assign a keyboard shortcut to dynamically activate a given LUT.

On the other side: it would be very convenient to have also a command line switch to activate a specific LUT.

I have 550 LUTs in mpv..here's a small sample of LUTs to give you an idea.

then for encoding LUTs into video use encodelut.lua (just part of it)
```
-- LUT3D cube filter
local homedir = os.getenv("HOME")
local lut = string.format("%s", mp.get_property_osd("lut"))
local lutnew = string.gsub(lut, "~", "")
local lutuserpath = "lut3d=" .. homedir .. lutnew
local settings = {
detached = true,
container = "",
only_active_tracks = false,
preserve_filters = true,
append_filter = lutuserpath,
codec = "",
output_format = "$f_$n.mp4",
output_directory = "",
ffmpeg_command = "ffmpeg",
print = true,
}
