Instead of having the l1 lines be inside the view space, move them to be inside their respective axis (with only a 16 unit portion inside the view) such that the clear price label can overlay with them nicely without obscuring; this is much better suited to multiple adjacent y-axes and in general is simpler and less noisy. Further `L1Labels` + `LevelLabel` style tweaks: - adjust `.rect` positioning to be "right" (i.e. inside the parent y-axis) with a slight 16 unit shift toward the viewbox (using the new `._x_br_offset`) to allow seeing each level label's line even when the clearing price label is positioned at that same level. - add a newline's worth of vertical space to each of the bid/ask labels so that L1 labels' text content isn't ever obscured by the clear price label. - set a low (10) z-value to ensure l1 labels are always placed underneath the clear price label. - always fill the label rect with the chosen background color. - make labels fully opaque so as to always make them hide the parent axes' `.tickStrings()` contents. - make default color the "default" from the global scheme. - drop the "price" part from the l1 label text contents, just show the book-queue's amount (in dst asset's units, aka the potential clearing vlm).
Goes back to always adjusting the y-axis range to include the L1 spread and clearing label in view whenever the last datum is also in view, previously this was broken after reworking the display loop for multi-feeds. Drops a bunch of old commented tick looping cruft from before we started using tick-type framing. Also adds more stringent guards for ignoring but error logging quote values that are more then 25% out of range; it seems particularly our `ib` feed has some issues with strange `price` values that are way off here and there?

New styling for our L1 spread labels drawn on the fast chart, again, in support of the oncoming #420.
