Summary of changes

BLOCK2 code-branch was missing handling for duplicate packets. As part of the fix, added also
a call to update the duplicate package data via a new function
sn_coap_protocol_update_duplicate_package_data_all.

The new implementation handles all CoAP messages, not just those with COAP_MSG_TYPE_ACKNOWLEDGEMENT.

Add also 4.13 (Request Entity Too Large) responses to duplicate info list.

Add client library configurations for DEFAULT_RESPONSE_TIMEOUT and SN_COAP_DUPLICATION_MAX_TIME_MSGS_STORED.

Increased the default timeouts of DEFAULT_RESPONSE_TIMEOUT and SN_COAP_DUPLICATION_MAX_TIME_MSGS_STORED to 300 seconds.
These two are critical parameters for low-bandwidth high-latency networks. The defaults should be more geared towards such networks that are likely to have issues with transmissions.
The increased defaults can increase the runtime HEAP usage when there is a lot of duplicates or retransmissions.
