Add an OpenCL filter for filtering GoPro Max native .360 files
into standard equirectangular or youtube equiangular cubemap (eac)
projection.
The .360 file contains separated two video streams.
This filter combine two streams into single stream with standard
format.

The patchwork failed, but it was caused by opencl.c (not by this patch):

with this patch it fails here on ubuntu:
/usr/bin/ld: libavfilter/libavfilter.a(opencl.o): undefined reference to symbol
'clBuildProgram@@OPENCL_1.0'
/usr/bin/ld: /usr/local/cuda/targets/x86_64-linux/lib/libOpenCL.so.1: error
adding symbols: DSO missing from command line
thx
I tested on Ubuntu 22.04, and it works fine.
As message shows, it seems the error is not related to this patch but OpenCL
library.
I found I have to add `gopromax_opencl_filter_deps="opencl"` in configure file.
I'll amend the patch later.
