Fixing output errors when use_vulkan_compute=True

1. net.opt.use_vulkan_compute=True/False has no effect at all:
   Solved, use pip install ncnn-vulkan

2. python core crash after extract, message Unknown error occurred when clearing extractor:
   Solved, use ex= net.create_extractor() instead of with net.create_extractor() as ex: (will there be a vram leak?)
   edit: vram leak confirmed, relates to reclaim_blob_allocator(), contacting to the maker of ncnn-vulkan thereafter.
   edit2: Made a ExtractorGPU for vulkan route, vram leak solved.

3. 256x256 output is blank:
   Solved, by adding:

net.opt.use_fp16_packed = False
net.opt.use_fp16_storage = False
net.opt.use_fp16_arithmetic = False

4. 256x(16n) output is blank:
   Unsolved,
   Output at node 35 (BinaryOp-Add, node16+node34) has a significant diff between cpu and vulkan when the input is a 512 (16x32) seq. A lot of its values became negative when on vulkan.
