Bugfixes & 1 second sensors

[timlaing]

• Added OptionsFlow to allow user selection of sensors required
• Added back 1 seconds sensors as I needed them for some automations
• Fixed deprecation warnings from HA core

I've already fixed the warnings in my dev branch but I appreciate it nonetheless. The OptionsFlow stuff is really nice and has been on my TODO list for a while. Unfortunately I cannot support the one second sensor, it's explicitly forbidden by Emporia and I'd rather not anger them (again). For context, see this discussion in the PyEmVue repo. magico13/PyEmVue#19

If you need the resolution at one second I would recommend flashing ESPHome onto the Vue hardware to get fully local access. You can of course run your own fork with whatever you want enabled, but Emporia might ask you to stop or choose to cut off your access/rate limit you.

Thanks for your feedback. I'll submit a different pull request for the options flow code.
