Vendor specific or custom characteristics

To format a characteristic value of a Vendor specific or custom characteristic (not defined in GATT specifications) there is a Characteristic Presentation Format Descriptor which defines the format of the Characteristic Value. So if this Descriptor is present it is possible to read it and get the characteristic value format, exponent, unit, name space and description.

To add custom characteristics it is possible to write a xml file describing the characteristic and provide a 128 UUID. Then this could be registered in bleak/bleak_sigspec.

Added in bleak_sigspec 0.0.4:

• Nordic UART TX, Nordic UART RX characteristics.
