POWER<x> data-point is defined as boolean but should be string

[Sineos]

Describe the bug
According to the Tasmota documentation the POWER accepts more than just boolean values:

With the current boolean definition, sending e.g. TOGGLE is not possible

Expected behavior
Accept string

Versions:

• Adapter version: 2.5.1

Additional context
I modified https://github.com/ioBroker/ioBroker.sonoff/blob/master/lib/datapoints.js to

POWER1:        {type: 'string', role: 'switch',                   read: true, write: true,  storeMap: true},

If acceptable I can launch a PR to modify the POWER Definitions to string

Note: In fact this would be a breaking change, because then also the role do not mtch anymore ... someone needs to look deeper into that
