Add Aliases for Amazon Echo Dot 3 & 4

[Mirabis]

Hi,

I kept track of the releases and heard Amazon Echo deices were supported - yay. However, after trying and trying I found out that the IDs are different when not using the official integration. There's a popular unofficial version (free) that is available on HACS but those use a different ID.

I added both the aliases as I have both devices in HA. Repo for custom component is: https://github.com/custom-components/alexa_media_player

There are also two other issues created where there are other model ID's referenced.

Let's also resolve that in this PR.

See #1568 and #1569

C78MP8 seem to be model id for Gen3 (In the original PR D91029T)
I cannot find anything in Google for D91029T, so I don't know where you got that model id from @wranglatang.

B7W644 for Gen4 (in the original PR B7W64E)
Only difference here seems to be the color, so B7W644 can be added as alias as well. @Mirabis Can you add that?

I just read the Model ID off the bottom of the device but i have recently noticed that when using the unofficial Alexa Media Player integration the model ID's are different. Seems like we have a few different options

Gen 3:

• D91029T - Bottom of Device
• ECHO A32DOYMUN6DTXA - Alexa Media Player Integration
• C78MP8 - Not sure where this has come from

Gen 4:

• B7W64E - Bottom of Device
• ECHO A2U21SRK4QGSE1 - Alexa Media Player
• B7W644 - Not sure where this has come from

Here is my Gen 3 Echo DOT Charcoal:

• C78MP8 - Bottom of device
• ECHO A1RABVCI4QCIKC - Alexa Media Player

My Gen 4 Echo DOT Glacier White:

• B7W64E - Bottom of device
• ECHO A2U21SRK4QGSE1 - Alexa Media Player

Hmm okay, so looks like different models for different colours -_- Maybe its best to just have the model as Gen3 & Gen4 and then the user just selects that in the GUI or code.

• My Black Echo Dot 4 (B7W64E) shows up as A2U21SRK4QGSE1 in the integration;
• @sockmonkey0223's Glacier White (B7W64E) Echo Dot 4 shows up as A2U21SRK4QGSE1 in the integration.

Those are identical, so most likely the model doesn't change for colour but for features. The version with clock has B7W644, other variants may have other IDs as well. Echo Plus Gen 2 reports as ALEGCNGL9K0HM for instance.

@bramstroker I've updated the PR for the specified issues and double checked the ID's in the other repo. More aliases should be added later on, but I do not have all the device types nor time (at the moment) to dig through the logs people post on the custom integration.

Thanks. Looks fine like this. Think we can merge.
Btw you don't have to touch supported_models.md next time. That will be autogenerated, so you can save time.
