Templates.is_scaled > Templates.is_in_uV

This needed to be done after #3794.
At the moement is is a simple replace in the entire code.
There are many return_scaled to be changed in return_in_uV but @zm711 already started to change some in #4033.
So lets wait #4033 to be merged first and then lets continue working on this.

I think we will need to make some logic for readi backward compatible Templates saved before 0.103.0

I was just commenting on this deprecation. We hadn't officially discussed deprecation strategy for scaled -> is_in_uV, which I think we should. Agree with backward compatability though! It was a pain once when we did a dep and all my analyzers started erroring. I forget what it was. nbefore maybe?

This is great, thanks Sam.
