Honor 6A Vignetting - New profile

[falket]

Should be ok (vignetting is perfectly fixed), for the entry i have tried to follow the huawei p10 lite entry profile added recently (for which i posted the vignetting entry).

I would be very happy to see also this entry included. Thank you in advance.

Vignetting data is the same of this closed issue: #251
