 These instances are registered with the `OTAImageProcessorImpl` instance, which manages the selection of processors that should process the next blocks, until a full TLV block was transferred.
 
 The application is able to define its own processors, thus extending the default OTA functionality. The application can also opt to disable the default processors (application, SSBL and factory data).
