Arm64-v8a support

[marcin-adamczewski]

Hi :)

I was trying to build mace sample on my OnePlus6T, however, as I can see there is no support for arm64-v8a processors. Both mace library and mace model is for armebi-v7a.
I've taken arm64 libmace.a file from the mace sample, however I'm not able to create cpm.a file for arm64. I've modified cpm.yml file target_abis to include arm64 and ran tools/converter.py convert --config=cpm.yml but the command doesn't finish, it just gets stuck.
Would you be able to provide cpm.a for arm64 or add support for arm64 in your sample projects?

Thanks in advance :)
