Library requires tools:replace in client AndroidManifest.xml

[AndyG]

First off, thanks for the wonderful library. Made certain requirements in my application a breeze!

Unfortunately, currently clients using this library must include tools:replace="allowBackup,android:label" for their apps to compile. This is due to the example library's manifest including

and

https://github.com/wasabeef/fresco-processors/blob/master/example/src/main/AndroidManifest.xml#L17

Please remove the samples from the published artifact so we won't have to manually override these attributes in our app.
