Contribution description
Allows the user to add CoAP Options out of option number order via the
coap_opt_add_[string|uint](pkt, ...)
functions. Implemented within the nanocoap_opt2_sort module.Conceptually, this PR accomplishes the same goal as #9144. However, I simplified the implementation based on test results. This PR automatically checks the sort order in
coap_opt_finish()
and sorts if necessary.Issues/PRs references
Based on #9474. Supersedes #9144. Implements ideas described in #9048 and #8831.
