Detailed Description

The fetch source manager allows for registration of multiple fetch sources to be used by the SUIT processor during manifest processing.

A fetch source is any module, that registers it's URI handler through the suit_dfu_fetch_source_register and provides downloaded payload chunks using the suit_dfu_fetch_source_write_fetched_data API. The SUIT proccessor iterates over the registered fetch sources, calling respective suit_dfu_fetch_source_request_fn.
