Add support for reading booleans from registers

[angelrti]

The Modbus adapter should be able to read single bits from a Modbus register and translate it to a DynamicData boolean field.
We may want also to apply so masks and compare them with a specific value ('result value'). For example
(register & mask) == 00001000

In this case, the output value might be an enum. Also, the 'result value' that we use to compare might be an enum value
