Removed the `experiment_start/end` dates. This is done because in the previous iteration with endorsement signaling, the recommendation was for the sender to set it to 1 and that could have had privacy concerns when first deploying given that the default was to downgrade the signal to 0. Now the recommended default for both sending and forwarding nodes is to set `accountable` to 0. Hence, the dates have been removed as nodes can start setting the signal without leaking information about being the sender.

LGTM - just a pre-existing issue with one of the markdown links.
Working on a LDK implementation which we can link as reference to fill in the outstanding TODO.

pre-existing: link should be to ./blip-0004.md, might as well fix while we're here!
