Synchronize On-Remote Volume Display with Receiver Volume Scale Setting

[jstrify]

Description

Per Denon documentation, receivers can be confirmed to display volume in a "Relative volume scale (-79.5 dB - +18 dB)" or an "Absolute scale. (0-98)".

I noticed that the Denon/Marantz apps will display volume on the slider using the scale configured in the receiver. However, it seems that the Remote Two will only display the results on the absolute scale. This makes sense to me - you send MVUP<CR> you get back absolute values from 00 to 98 (ex. MV005<CR> or MV80<CR>).

I think it would be great if this integration could either:

1. Read the "Scale" setting set in Settings --> Audio --> Volume (unclear from documentation I found on the IP protocol and the denonavr code I've read thusfar if this is possible...)
2. Add a toggle to the integration that would let me set whether I have configured an absolute or a relative scale.

I guess the problem is, a Media Player entity only allows for value from 0 to 100. See https://github.com/unfoldedcircle/core-api/blob/main/doc/entities/entity_media_player.md#attributes

I think the python denon library is aware of this and the integration has to convert correctly for the absolute scale.
