Strobealign aemb

[wwood]

Thoughts @AroneyS ? Tests pass on my machine, something is wrong with the CI atm. It basically just runs strobealign --aemb, but can output dense or sparse, takes multiple refs and readsets etc, so a little more ergonomic.

Still needs to make a cached strobealign index if there are multiple readsets for a single reference. Also seems like it wouldn't be hard to adjust to genome mode too, just by taking a length-weighted average of the means it predicts.

Unfortunately it can't be used as a drop-in replacement for binning, because it only reports mean, not variance.

Once this is through, can copy the template so we can use fairy as well (apparently using it as an API isn't well supported).

CI issue might be due to mambaforge sunsetting or mamba 2.0 (conda-incubator/setup-miniconda#366). Bin Chicken's CI broke too, was fixed by removing mamba from the test workflow yml.

Also, cargo test errors locally for me:

  --- stderr

@AroneyS CI fixed - thanks for the tip. That looks like a strange linking error when you are running cargo test locally. Does the code make sense though?
