Medics to have ability to Cancel Medic Request

[HunterB]

Often times I have found myself to be locked in by a medic, only for them to either not show up, be killed, or to be drawn to another death that is closer.  I think it would be a cool idea that a medic could send a request back to the dead player or just cancel the request so they aren't locked in for "x" amount of time.  Usually is not a big deal to wait, but sometimes people want to get back in the fight and if the medic does not think they are going to be able to make it, they have control of reversing the request.

Ngl the current request system is kinda scuffed and needs a rework either way, adding it to the board for later todo's
