WIP: smartlock_c34: add initial support

[jarodwilson]

This is an attempt to add support for the Eufy Smart Lock C34 device.

Related: #578

I'm currently seeing the lock show up in homebridge's eufy-security plugin, with proper state, battery level, and getting lock/unlock notifications. However, something is still not quite right with lock station init, as I can't actually get a connection to the lock to issue lock/unlock commands, for reasons that are as of yet beyond me.

...and I just saw in #528 that the C33 doesn't use p2p lock/unlock commands, it's using mqtt, and I'm going to bet the C34 does the same. Ugh.

The lock does have matter support, but it seems to lose connection frequently, and drain the lock battery at a rather prodigious rate, so I had stopped using it. :(

@jarodwilson what is the status on this PR? Is it tested?

[jarodwilson]

This one is still in need of some attention, marking it as a WIP. I've been sidetracked by several other projects, need to get back to this one day, but had been waiting on the camera bits to progress first. :)

Is there any plan to implement this, even in the incomplete state? While not being able to lock and unlock it is a bummer getting the state and battery level would be really useful for implementations

[jarodwilson]

Not from my side, I've not had any time to work on this, and newer firmware improved the battery drain rate somewhat with matter, and I'm simply connecting to the locks over matter w/my HA install.

Thanks for the confirmation, I'll check redeploying the lock over matter
