support adaptive icon

[fisherWang2017]

It seems that pkg.Icon(nil) fails if apk uses adaptive icon format

@fisherWang2017 I just found some random apk and got icon error. Is this a same case? File: file.apk.zip

this code fixed my same problem

icon, err := pkg.Icon(&androidbinary.ResTableConfig{
    Density: 720,
})

Adaptive Icon is available from SDK Version 26.
So, adding SDKVersion: 25 may be a workaround.

icon, err := pkg.Icon(&androidbinary.ResTableConfig{
    SDKVersion: 25,
})
