[Feature, DA] Add reuploading to analog feature maps

[madagra]

In the analog feature map constructors, reupload data by applying a few different analog rotations in sequence with a different reupload scaling. This can help training in some cases.

@jpmoutinho How urgent this is ?

IMO not urgent, but would depend on requests from users.
