Added support for Matter OTA firmware

[rhilseth]

This PR adds support for detecting Matter OTA firmware (https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/protocols/matter/overview/dfu.html#matter_ota_image_structure_and_transfer) and also extracting the firmware payload itself.

Example output for the file https://prod.ota-updates.bosch-smarthome.com/v1/updates/BTH-RAD/BTH-RAD_Prod_2.0.9.ota found via the DCL UI at https://webui.dcl.csa-iot.org/models

The test file in tests/inputs has been created manually with a dummy payload.

This looks good to me, aside from the noted sanity checks that should be performed to prevent crashes/exceptions in the event of malformed/corrupted data. Once those are addressed, I'll merge the PR. Thanks!
