Update device_capabilities.py: Add GTX 1070, 1080; main.py: timeout 90->900

[FFAMax]

1. Added few GPUs.
2. Tuned timeout. On slow setups (~1 token per second) average response may take ~600-1000 tokens. In most cases it will lead to timeout (network error which is not). Fixing to reduce exceptions. Who looking for better performance and know what to do need adjust with a knowledge how it will impact. By default making it will work for most cases.

Can you double check the FP16 numbers here? Those look a little too low. They are usually halfway between the 8 and 32.

For example take GTX 1080 Ti

According to https://images.nvidia.com/aem-dam/en-zz/Solutions/design-visualization/technologies/turing-architecture/NVIDIA-Turing-Architecture-Whitepaper.pdf

FP16 & INT8 are NA

Based on https://www.techpowerup.com/gpu-specs/geforce-gtx-1080-ti.c2877
FP16 (half) 177.2 GFLOPS (1:64)
What is .177 TFLOPS as mentioned

So they are low probably due no HW support or something like that.

For example for https://www.techpowerup.com/gpu-specs/geforce-gtx-1660-ti.c3364 We can see 2:1 as you mentioned while for 1080 it is 1:64
