Update mbed-coap to version 5.1.4

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.
