Esparagus HiFi MediaLink

Hey Folks. HiFi Esparagus S3 version is here. 

What has changed?
Well, 

- It is ESP32-S3-based, so it works considerably better with ESPHome with extra CPU power and extra RAM.
- It adds an onboard mic, so voice-assist config is supported.
- It moves the IR and RGB LEDs to the front side

- The relay driver is once again available from the back. Not that it is in high demand, but it cost me pennies to get it back

Docs are updated, ESPHome configs are there as well. squueezelite configs is there. Snapclint build is coming soon, just need to test it.

Hey everyone.
I passed the formalities necessary to actually start a Crowd Supply campaign to support production of the Esparagus series boards. 

If you're a hobbyist maker it is actually very hard to produce these small projects in small volumes, because of fundamental costs of initial development. When you know in advance what kind of volumes you should expect to produce, it is much easier to build up an adequate price for the unit. 

Public campaigns also help to understand if a product is finally ready for a launch, as adding improvements and new features is a never-ending effort. At some point you have to say "Although it's not perfect, it's sufficiently near".

I invite everyone interested to subscribe to campaign updates, as in coming weeks I will need to work hard to finalize the design and prepare for the production run, which will strongly depend on the community interest.
