Cannot construct RSCPData with data type NONE

[bvotteler]

Validation fails when attempting to build a RSCPData instance with data type of RSCPDataType.NONE via

RSCPData.builder().tag(RSCPTag.TAG_EMS_REQ_POWER_PV).valueOfType(RSCPDataType.NONE, new byte[0]).build();

Expected: Can build an instance.
Actual: It throws an IllegalStateException with the message: Data must not be empty.

Fixed with version 1.0.1

Also added a helper method in the builder called noneValue() to add an empty byte array with data type NONE.

For example, the following two ways of constructing a RSCPData instance holding NONE are equivalent:

RSCPData.builder().tag(RSCPTag.TAG_EMS_REQ_POWER_PV).valueOfType(RSCPDataType.NONE, new byte[0]).build();
// same as
RSCPData.builder().tag(RSCPTag.TAG_EMS_REQ_POWER_PV).noneValue().build();

Thank you to bjoernbrings for pointing this out!
