add invert output option

closes #408

another one need a conflict correction 😄

overall looks good but there is one more thing - when constructing components, we need to reset output to non-inverted as a common baseline, so for example if you change switch into window covering, that know nothing about inverting outputs, outputs do not remain inverted.
it's not ideal, and represents a leak in abstractions, so if you have better idea how to manage it - welcome.
but for now, we'll need something similar to this.

we have in_inverted, let's call this option out_inverted

Maybe I miss something, but I think we don't need to reset it. inverted is a config property of sw, which means that if the user switches from sw to window it reboots the devise which means a new output is created and which will use the wc setting and will never be in inverted mode.

it reboots the devise

except it doesn't. *restart_required = true does not mean reboot, it means HAP server restart.
HAP server gets stopped, components get destroyed and re-created. however, peripherals - the Inputs, Outputs, temp sensors, etc, do not. so if inverted setting would be preserved and new components created with inverted output(s).
