New beeswarm algorithm

[jkrumbiegel]

I noticed that the default algorithm is a bit buggy with overlaps, and it doesn't look ideal in the places without overlaps either. So I came up with my own version (I'm sure I just reinvented one of the ones out there, but whatever, was a fun exercise).

This one's as quick as the default but looks much more even, without overlaps.

Before

Random.seed!(1233); beeswarm(fill(1, 2000), randn(2000), markersize = 5.5, alpha = 0.5, direction = :x)

Random.seed!(1233); beeswarm(fill(1, 200), randn(200), markersize = 18, alpha = 0.5, direction = :x, marker = Circle)

After

Random.seed!(1233); beeswarm(fill(1, 2000), randn(2000), markersize = 5.5, alpha = 0.5, direction = :x, algorithm = SwarmMakie.SimpleBeeswarm2())

Random.seed!(1233); beeswarm(fill(1, 200), randn(200), markersize = 18, alpha = 0.5, direction = :x, marker = Circle, algorithm = SwarmMakie.SimpleBeeswarm2())

This includes commits from #26 so that one should be merged first

Should we rename this? Maybe make this SimpleBeeswarm and rename the current default?

[jkrumbiegel]

Yeah I think that would be good. Do you actually still want to keep the current default given that it causes overlaps?
