arc supports; mitigations for warping / higher temperature printing

[Fire-]

Hey, this is FANTASTIC! I don't currently have the brain cells to contribute this myself, so I wanted to at least note these thoughts down

We may be able to get away with higher temperature printing and/or minimize arc-layer warping by growing supports to the nucleation site of each arc. The frequency of added supporting structure can be a function of print temperature and print speed, as the amount of support required for this kind of overhang goes up when available cooling time goes down. Pillar supports would likely be the simplest, while tree supports would be the least wasteful, at the cost of computation time.

We can increase the available cooling time as arcs shrink by controlling the order we print each arc depth to avoid building off of fresh arcs that haven't reached a minimum cooling time; this will come at the cost of print head travel time.

might not need support at the nucleation so much as the corners, as those warp quite a bit
